All about greenhouse-nano polycarbonate

What you need to know about cellular polycarbonate?

In cross-section, the sheet is more like a honeycomb, in the form of a rectangle or triangle, hence the name of the material itself. The raw material for it is granular polycarbonate, which is formed due to the condensation of polyesters of carbonic acid, plus dihydroxyl compounds. The polymer belongs to the group of thermosetting plastics, it really has many unique features.

Industrial production of cellular polycarbonate is possible due to the use of extrusion technology from granular material. The production is organized according to the technical conditions TU-2256-001-54141872-2006. This document is considered the basis for the certification of material in our state.

The leading parameters, as well as the linear dimensions of the panels, must necessarily comply with regulatory requirements.

Before you buy cellular polycarbonate, you should take into account that its structure is different:

What is the best thickness of polycarbonate for the greenhouse

• portable and stationary greenhouses for seedlings - 3 mm, 3.5 mm;
• arched seasonal backyard greenhouses - 4 mm;
• drip-shaped garden and horticultural greenhouses - 4 mm;
• classic greenhouse cover "house" with a gable or sloping roof - 6 mm;
• wall-mounted single-slope greenhouses with an abutment to the house - 6 mm, 8 mm;
• vertical glazing of industrial greenhouses - 10 mm, 12 mm;
• insulation of windows of livestock complexes, cowsheds, pigsties - 12 mm;
• hangar-type capital farm greenhouses - 14 mm;
• stationary heated tunnel-type greenhouses - 16 mm;
• greenhouse complexes based on hydroponic systems - 18 mm.

GREENHOUSE-nano honeycomb sheets are modern polycarbonate for greenhouses and livestock complexes, a new generation covering material that helps to mobilize the internal biological potential of plants and animals. It is used to cover greenhouses on a personal plot, in industrial plant growing, as well as for glazing livestock buildings.

Why do you need cellular polycarbonate, the scope of its use

Cellular polycarbonate is justified in construction, it is used in the roof, sometimes in the enclosing structures. This material, taking into account its exceptional properties, is often used in the release:

• awnings over exit doors;
• arches;
• carports;
• canopies for public transport stops;
• greenhouses;
• soundproof screens next to railway tracks and high-speed roads.

In private houses, it is relevant to glaze gazebos, verandas and attics, another area of ​​use is equipment for agricultural greenhouses, which will turn out to be durable structures.

Polycarbonate GREENHOUSE-NANO - a special material for greenhouses and agricultural facilities

Cellular polycarbonate GREENHOUSE-NANO is an innovative Russian material for covering greenhouses, which increases the yield of vegetable crops in greenhouses by up to 48%. Due to the content of special nanostructured additives, greenhouse polycarbonate GREENHOUSE-nano creates the effect of light radiation of 660 nm, useful for plants, corresponding to the peak of photosynthesis, thereby accelerating fruit ripening for 3-4 weeks. This product is specially designed for the cultivation of agricultural vegetables in greenhouses, and has a beneficial effect on the growth and development of plants. The nanostructured material in the composition of the honeycomb sheets forms a special favorable microclimate inside the greenhouse, similar to the greenhouse effect, which contributes to a significant increase in the yield of vegetables in various cultivation facilities.

The new polycarbonate for greenhouses GREENHOUSE-nano from the Belgorod manufacturer PLASTILUX-GROUP is an improved model of the earlier GREENHOUSE sheets, with added light conversion properties and an extended 10-year warranty. The improved material with the prefix "nano" has the same anti-fog coating, which has the property of hydrophilicity and prevents the formation of large drops of condensation on the inside of the polycarbonate boards. The new product with a pink tint not only retains all the advantages of the transparent GREEN HOUSE material, but also ensures the conversion of harmful UV rays into a spectrum of light radiation useful for plants. A “smart” selective additive inside the panels converts hard ultraviolet light into the red spectrum, which stimulates the activity of plant life processes. Thanks to the synergistic action of two nanocomponents - "antifoga" and an agro-additive, ideal conditions are created for growing fruit crops in greenhouses made of GREENHOUSE-nano polycarbonate.

Light pink PLASTILUX GROUP panels have similar light transmission values ​​with transparent sheets, but are more beneficial for plants due to their light-transforming effect. Pink polycarbonate for greenhouses GREENHOUSE-nano with a thickness of 6 mm is a unique innovative product for small greenhouses that allows you to start growing vegetables for sale almost a month earlier. This increases the efficiency of small agribusiness to the level of profitability of industrial greenhouse complexes of 30-35%. The highest yield per square meter - 6-7 kilograms - was observed in early-maturing squash of the "Umbrella" variety. Some fruits reached a weight of 2 kg (an increase of 60%).

GREENHOUSE-NANO honeycomb sheets are recommended for use in private households as an alternative material for covering greenhouses (a greenhouse film substitute), as well as in the agricultural sector of the economy to increase the efficiency of industrial livestock and crop production.

Sheet thickness, specific gravity

The production technology guarantees the possibility of producing cellular polycarbonate of various standard sizes. At the moment, the industry produces panels, the thickness of which is 4, 6, 8, 10, 16, 20 and 25 mm, taking into account the different internal structure. The density of polycarbonate is usually 1.2 kg / m 3, determined by the measurement method, which is stipulated by the DIN 53479 standard.

For panels, this indicator fluctuates depending on the thickness of the material, plus the number of layers, another step of the stiffeners, and also the cross-sectional area.

For many well-known brands of cellular polycarbonate, the data is indicated in the table:

Monolithic polycarbonate: features and applications

This is a cast sheet material (GOST R 51136) without internal voids, similar in optical properties to quartz glass.

The molded thermoplastic polymer is ideal for the production of precision parts for the optical and electrical industries, as well as in the construction industry - wherever transparency, thermal resistance and high impact resistance are required:

• in the automotive, aerospace and photo-optical industries - for the production of machine parts, rotors for pump casings, fans, counters, parts of telephones, cameras, lighting devices on the edges of aircraft wings;
• in the production of household appliances, industrial and electrical equipment;
• for glazing elements of buildings subject to vandalism, industrial and glazing of residential buildings and structures (dormers, winter gardens);
• manufacture of windows in airplanes, medical equipment, helmets for astronauts and F1 pilots.

PC plastic has several markings:

• NR - anti-reflective coating.
• PC-HT is highly heat resistant.
• AR - increased hardness.
• FR - increased fire resistance.
• FG - Approved for food contact.

Along with the above advantages, the choice of polycarbonate is also due to its affordable price, which makes this solution very beneficial in all aspects.

# 1. The main advantages of polycarbonate

Why is this relatively new material instantly conquered by summer residents throughout the country and by leaps and bounds displaces film and glass from the sites? The reasons for the popularity should be sought in the features of the structure of the material. On an industrial scale, polycarbonate began to be produced in the 60s of the last century, it was used in many areas of construction and industry, and a material suitable for greenhouses appeared a little later at the suggestion of Israeli scientists.

For arranging greenhouses, only cellular polycarbonate is used - a monolithic analogue is heavier, does not have sufficient strength and thermal insulation qualities. The material consists of two or three parallel plates connected by jumpers. The latter play the role of stiffeners, and the space between them, filled with air, increases the thermal insulation qualities of the material. The structure of the sheet can be single-chamber, double-chamber, etc.

The main advantages of cellular polycarbonate for greenhouses:

• excellent transparency and ability to scatter sunlight. Up to 92% of the sun's rays pass through colorless polycarbonate, which has a positive effect on the crops grown. Moreover, the material with a special protective film allows you to protect plants from hard ultraviolet radiation that is harmful to them;
• light weight. This parameter depends on the thickness of the sheet, but even the thickest material will weigh several times less than its glass counterpart, which reduces the load on the greenhouse frame;
• flexibility and plasticity. Cellular polycarbonate can be bent during installation, creating arched greenhouses;
• good mechanical strength. From the impact, the material will not tear like a film, and will not break into fragments like glass. The thicker polycarbonate is chosen, the more difficult it will be to break its integrity;
• excellent thermal insulation properties due to the honeycomb structure of the material. Heating costs can be minimized. The soundproofing qualities of the material are also at a height - on average, it can reduce noise by 22 dB;
• resistance to temperature extremes, winds, mold, fire.

The durability of high-quality polycarbonate exceeds 10 years, and conscientious manufacturers give a guarantee of up to 15 years. Among the disadvantages of the material is instability to sunlight, like any plastic, but thanks to a special film coating, it was possible to get rid of this disadvantage. Cellular polycarbonate has no other significant drawbacks, especially in comparison with other covering materials for greenhouses - the main thing is to buy high-quality material, and not a handicraft product.

Usually cellular polycarbonate is produced in sheets with dimensions of 2.1 * 6 m and 2.1 * 12 m, less often 2.1 * 2 m, but the thickness can vary within wider limits (3.5-16 mm), and it is from it mostly depends on the basic parameters of the material.

Distinctive characteristics of GREENHOUSE-nano polycarbonate

How thick can it be?

In addition to density, the list of key criteria for selecting the optimal type of material for the construction of greenhouse structures also includes the thickness of the profile sheets. At the same time, it is strongly recommended not to choose the extremes in one direction or the other. That is, in each specific case, we are talking about the so-called golden mean. If you give preference to sheets that are too thin or thick, the structural strength or light transmission will suffer.

In accordance with the recommendations of specialists and the reviews of experienced summer residents, the optimal indicator varies in the range from 4 to 8 mm. At the same time, when making a choice in favor of the upper limit, it should be borne in mind that we are talking about the most dense sheets, which will transmit light worse. They are relevant mainly for the construction of winter structures, that is, when maximum strength is put at the forefront.

When choosing a PC by thickness, a whole list of determining factors should be taken into account.

1. Climatic features of the region, such as the nature and amount of precipitation. This is mainly about snow and means the potential load on the future structure.
2. The prevailing direction of the wind and the maximum force of its gusts.
3. The material from which the greenhouse frame will be made. Naturally, the most durable are metal structures. The timber frame has a lower load-bearing capacity.
4. Distance between the flooring battens and the frame itself. The closer to each other the elements of the future structure are located, the higher its strength will be. In such situations, you can choose polycarbonate with a lower thickness.
5. Seasonality of operation of the structure. So, if planting will be carried out in spring and summer, then there is no need to use thick PC sheets. If we are talking about year-round operation of a greenhouse for growing crops on an industrial scale, then it is worth stopping at a thicker polycarbonate.

It turns out that the thickness of the material when choosing is determined primarily by the features of the operating conditions. Based on the scope of application, polycarbonate sheets can be distributed as follows:

• 4 mm - greenhouses small in surface area;
• 6 mm - greenhouses with a small area;
• 8 mm - large greenhouses;
• 10 mm - glazing of large greenhouse structures;
• 16 mm - due to the increased density and rigidity, the material is used in the construction of entire greenhouse complexes;
• 20 mm - construction of winter gardens and greenhouses.

According to the advice of experienced craftsmen and users, for a medium-sized greenhouse, the best solution would be to choose polycarbonate with a thickness of 6 mm. This approach to the choice of materials will be most relevant for regions where moderate snow activity prevails.

Mechanical strength characteristics of cellular polycarbonate

Panels, taking into account the honeycomb structure, easily cope with heavy loads. In parallel with this, the surface of the sheet is subjected to abrasive action, taking into account prolonged contact with small particles, for example, sand. It is possible that scratches are formed when the material comes into contact with a rough surface with sufficient hardness. In general, the indicators of the mechanical strength of polycarbonate, by and large, depend on the brand, as well as the structure of the material.

During the test, the panels showed the following results:

How should cellular polycarbonate be checked taking into account strength indicators? Suffice it to compare the figures with the ISO 9001: 9002 standard.

The manufacturer usually guarantees excellent performance for 5 years, taking into account the correct installation of the sheets, as well as the use of certain fasteners.

Temperature level during operation of cellular polycarbonate

It is clear that cellular polycarbonate perfectly tolerates adverse influences from the outside, the operating temperature as a whole depends on the brand of the material, the quality of raw materials, and compliance with a number of production technologies. For most of the variations of such panels, the optimal temperature regime is from -40 degrees to +130 degrees Celsius.

Certain types of polycarbonate can cope with extremely low temperature conditions, of the order of -100 degrees Celsius, and the structure of the material will not collapse. When the material is heated and cooled, its linear size begins to change. The coefficient of linear thermal expansion in this case is 0.0065 mm / m ° C, calculated in accordance with DIN 53752. The maximum permissible expansion of cellular polycarbonate cannot exceed 3 mm per 1 m, and this applies to both the length and the width of the sheet. In general, it is clear that the material has a certain thermal expansion, for this reason, during its installation, appropriate gaps should be left.

How cellular polycarbonate changes, taking into account the temperature regime.

Scope of use

Due to the fact that GREENHOUSE-nano is made from modern materials and on modern equipment, it has excellent properties, among which the following are worth noting.

• Light conversion. UV rays, passing through the polycarbonate sheet, are converted into useful light that does not harm either animals or plants. This property helps to accelerate crop growth by as much as 4 weeks.
• Productivity. Polycarbonate has such good technical parameters that it completely protects the soil and thereby increases crop yields.

In addition, this material is anti-condensation and has a protective function for crops. It is widely used not only in agriculture, but also in other fields of activity. GREENHOUSE-nano polycarbonate is used for mounting:

• greenhouses (both small and large);
• livestock complexes;
• garden gazebos;
• open verandas;
• terraces, fences, outbuildings.

We can easily say that GREENHOUSE-nano polycarbonate can be installed instead of glass, metal profiles and, of course, instead of the usual film on greenhouses.

For more information about GREENHOUSE-nano polycarbonate, see the video below.

Species overview

Monolithic polycarbonate sheet can be solid and profile, can be classified by size and weight, color characteristics and other parameters. In most cases, a transparent material with stable geometric characteristics is used. But there are also non-standard versions of this lightweight plastic, which also deserve attention. It is worth considering them in more detail.

By form

Profiled monolithic polycarbonate is in many ways similar to the analogue of galvanized metal. It can have a different type of relief. The most commonly used are 2 options.

1. Wave. There are 2 height parameters. The wavy relief can be 18 or 34 mm deep, 76 and 94 mm wide. This option is especially popular when designing decorative structures and fences.
2. Corrugated trapezoidal. With a classic "fence" or "roof" profile. This is the optimal solution for external cladding of sheds, buildings, arbors. Trapezoid sizes range from 37 × 69 × 18 mm to 69 × 101 × 18 mm.

Flat or classic sheet version without corrugation, simple shape, looks more like silicate or acrylic glass.This is the optimal option in terms of translucency, but its strength is significantly lower in comparison with the corrugated one. Flat sheets are also textured - with a kind of embossing on the surface. Such options are not transparent, but retain high light transmittance.

Monolithic polycarbonate with a profiled surface type is often used as translucent inserts in roof structures. It transfers loads much better due to additional stiffening ribs. This is an analogue of slate or metal profile, which can be easily integrated into an existing coating or used as an independent version of the roof.

By color

Transparent monolithic polycarbonate occurs most often, it is popular and in demand. In terms of translucency, this type of sheet is not inferior to glass. It is well suited for arranging greenhouses, creating panoramic glazing, winter gardens. Its matte counterpart has a light transmittance of about 45-50%, perfectly diffuses the sun's rays, and protects from prying eyes.

The color palette of painted sheets is quite varied. These can be the following tones:

• White;
• lactic;
• black;
• Gray;
• Brown;
• turquoise;
• green;
• yellow;
• metallic.

Some manufacturers are making color polycarbonate even more varied with limited editions in the full RAL color palette. But in free sale it can be seen very rarely.

Industrial polycarbonates

Thermoplastics can be processed using the following technologies:

1. injection molding at 280-320 ° C - this is how monolithic polycarbonate is obtained;
2. extrusion from granules at 240-280 ° C with cold and hot forming - a method of manufacturing a honeycomb PC;
3. casting from solutions in methylene chloride - obtaining films from thermoplastic polymers.

To improve the parameters of strength, rigidity and stability at high temperatures, industrial polycarbonates are additionally reinforced with fiberglass, modified with light and / or heat stabilizers:

• PC modifications with higher fluidity are used to obtain products with a large area.
• PC varieties, reinforced with fiberglass mesh (10-40%), are characterized by increased rigidity and resistance to cracking.
• Modifications with additives of graphite, molybdenum sulfite or Teflon provide the plastic with increased smoothness and abrasion resistance.

Copolymers with halogenated bisphenols, in particular with tetrabromobisphenol, are characterized by reduced flammability. The use of bisphenol S for copolymerization increases the toughness.

Application of cellular polycarbonate

Mounting scheme for thermowells on polycarbonate.

Rigid ribbed sheet material has been specially designed to be installed as a durable roof slab that can withstand hail and snow. It is a durable, lightweight and transparent building material. But recently, cellular polycarbonate, thanks to its unique properties, has received even greater opportunities, and its use in many industrial areas, including construction, has expanded significantly.

Today, the use of cellular polymer material is carried out not only in the form of roofing material and vertical glazing of buildings, greenhouses and balconies. It is effectively used in the manufacture of protective and decorative partitions, which can be flat or profiled, as well as with additional elements of internal lighting.

But if we compare the use of two types of polymer material in the field of construction, then cellular polycarbonate, in comparison with the monolithic type, is more popular among specialists and private developers due to its exceptional properties and qualities.The widespread use of polycarbonate in the construction of industrial facilities and the private sector directly affects the increase in the production of this type of material.

Distinctive qualities of cellular polycarbonate:

Point scheme fixing polycarbonate sheets.

• high temperature resistance and fire resistance of the material;
• extreme lightness, that is, cellular polycarbonate weighs 3 times less than acrylic, and 16 times less than ordinary glass of a similar thickness;
• high light transmission and transparency of the material is up to 86%;
• low thermal conductivity and high thermal insulation properties;
• high impact strength, for example, cellular polycarbonate with a low weight is 8 times stronger than acrylic plastic and 200 times stronger than glass;
• high resistance to various chemical reagents;
• good sound insulation;
• the material is highly resistant to bending and tearing;
• the material is especially resistant to various atmospheric influences;
• cellular polycarbonate is distinguished by its durability, without changing the basic properties during 12 years of operation;
• the material is a good protective agent against ultraviolet radiation;
• excellent structural capabilities allow you to create original structures from light and durable sheets of cellular polycarbonate;
• during installation work and during operation, the sheets of this material do not break and do not crack.

Which polycarbonate is better for a greenhouse - honeycomb or monolithic

The main function of the greenhouse is to ensure the optimal temperature and humidity conditions necessary for growing crops in significant volumes. To solve this problem, structures are needed that cover rather large areas. It is possible to erect such a thing only when using materials with a low specific gravity, otherwise a strong and, as a consequence, a heavy frame will be required.

Cellular polycarbonate, which has a hollow structure, meets these requirements in the best way. In comparison with monolithic material, this material has a significantly lower specific gravity with the same sheet thickness. So, one square meter of a 10-mm panel of cellular polycarbonate is more than an order of magnitude lighter than a solid sheet of the same chemical composition.

In addition, cellular polycarbonate, due to its hollow structure, has a lower thermal conductivity. This circumstance is decisive when deciding on the choice of cover for greenhouses.

Monolithic polycarbonate sheets.

Cellular polycarbonate sheets.

So we decided that a greenhouse needs cellular polycarbonate, but which one is better from among the wide assortments on the market? This coating is selected based on a set of various properties and characteristics, the list of which includes the following:

• mechanical strength;
• resistance to changing environmental conditions;
• thermal conductivity;
• light transmission;
• the presence of protection against hard ultraviolet radiation.

Cellular polycarbonate has high parameters in all of the above positions, information on the technical characteristics of the panels is presented in the table:

The characteristics of cellular polycarbonate depend on two main factors: the quality of the raw materials and strict adherence to the material production technology. The panels are manufactured by extrusion using special equipment. Different manufacturing companies use raw materials that differ in properties, and their material structure may differ.

The above factors are taken into account when choosing a specific brand of cellular polycarbonate for the construction of a greenhouse.In addition to the above parameters, the cost of the panel is of decisive importance, which directly depends on the thickness and quality of the sheet.

Cheap materials, as a rule, are made in violation of technical conditions and they are not able to withstand long-term operation.

Resistance of the material to chemical compositions

The panels used in decoration are often influenced by various destructive factors. Cellular polycarbonate is resistant to most chemical inert compounds and compounds.

Do not use sheets in contact with such materials:

• cement and concrete;
• plasticized PVC;
• insecticidal aerosols;
• strong detergents;
• sealants containing ammonia, alkali or acetic acid;
• halogen and aromatic type solvents;
• solutions of methyl alcohol.

Polycarbonate is not afraid of a number of compounds, as it is chemically resistant, for example:

• concentrated mineral acids;
• salt solutions with a neutral, also acidic reaction;
• many types of reducing agents, even oxidizing agents;
• alcoholic formulations, excluding methanol.

During the installation of sheets, silicone sealants should be used, as well as certain sealing parts developed for them, as an option - EPDM and analogues.

Operation period

Manufacturers of cellular polycarbonate insist that the material retains its personal technical characteristics over 10 years of operation, taking into account the rules of installation and maintenance. The outer surface of the sheet has a special coating that guarantees protection from ultraviolet radiation. Its damage, naturally, shortens the service life of the panel and provokes its premature destruction. In places where the risk of mechanical damage to polycarbonate is not excluded, it is better to use sheets with a thickness of 16 mm or more. When installing panels, the need to exclude contact with compounds, the prolonged influence of which can lead to destruction, is taken into account.

Application of monolithic polycarbonate

Diy polycarbonate greenhouse scheme.

For many years, monolithic polycarbonate has been a recognized material among anti-vandal plastics. In terms of impact resistance, it exceeds ordinary glass by 250 times and acrylic glass by 10 times.

Due to these qualities, it is widely used in construction for the glazing of museums, waiting rooms, telephone booths and transparent fences. Suspended cabins for cable cars, hockey rink boards, protective motorcycle helmets and shields for law enforcement officials are made from this material.

Application in construction of this type polycarbonate material guarantees reliable protection against any acts of vandalism. At the same time, monolithic polycarbonate differs from other types of plastic in its special frost and heat resistance, since it can withstand the temperature range from -50 ° C to + 120 ° C. And such an important factor as the high endurance of fire makes it possible to use it in the construction of fireproof partitions for industrial and residential buildings.

Applications of polycarbonate

Scheme of structures made of cellular polycarbonate.

Since this polymer material ideally combines high mechanical strength with low water absorption, while maintaining its stable dimensions, it is successfully used for the manufacture of structural and electrical insulating devices. As well as high-precision tools and parts, housings for household and electronic equipment. Possessing high chemical resistance, polycarbonate is successfully used in various aggressive environments; no chemical and physical changes occur with the material itself.

All the listed properties of this polymer material made it possible to use it, replacing non-ferrous metals, alloys and silicate glass.Polycarbonate is widely used for the manufacture of parts for electronic equipment and color televisions, cases and covers for batteries, telephones and other high-precision and complex equipment. The relatively good optical properties of polycarbonate have led to its use in the production of lighting parts for cars, equipment for mines, road signaling and telephone disks.

Installation diagram of a polycarbonate greenhouse.

The biological inertness of the polymer material and the sterilization of products made from it made it possible to use polycarbonate in medicine. For example, blood vessels, drill bodies, dentures, Petri dishes and much more are made from it. Based on the use of polycarbonate, milk bottles, pipes for transporting milk, juices, beer and wine are produced. It is also used to produce dishes, parts for refrigerators, mixers, dishwashers and washing machines.

Today, polycarbonate is widely used in construction. It is used for the manufacture of windows, awnings, canopies and wall partitions. Greenhouses, greenhouses are assembled from whole sheets of polymer material, gazebos and verandas are equipped. The use of polycarbonate in construction provides an excellent opportunity to quickly and efficiently erect the necessary structures in industrial sectors and in a private courtyard.

Scopes of polycarbonate:

• in the automotive industry - 20%;
• in the production of optical glasses - 20%;
• in the production of window glass - 20%;
• in the production of equipment and machinery - 15%;
• in the production of consumer goods - 10%;
• in the leisure industry - 10%;
• in medicine - 5%.

Structure of honeycomb polycarbonate sheets:

	2H - two layers with rectangular cells;
	3X - three layers with a combination of rectangles, with additional oblique divisions;
	3H - three layers with rectangular honeycombs, with a thickness of 6, 8, 10 mm.
	5W - five layers with rectangular honeycombs, with a thickness of 16 - 20 mm.
	5X - five layers, which include straight and oblique ribs, with a thickness of 25 mm.

Sometimes panels are produced with other parameters, apart from those indicated earlier, this is all agreed with the customer on an individual basis. The thickness of the stiffeners is determined by the manufacturer, the maximum permissible deviation, in this case, is not established.

What is the bottom line

Plastilux Group (Belgorod) is one of the largest producers of polycarbonate sheets in Russia. It produces both standard honeycomb and monolithic profiled polycarbonate. Unlike competing materials, polycarbonate sheets of different classes differ from each other not only in specific gravity, but also in the composition of the polymer mixture.

The main brands of Plastilux:

• ULTRAMARIN - lightweight cellular polycarbonate of economy class with enhanced protection against UV rays and a biocide in the composition (a substance that prevents the growth of microorganisms).
• SUNNEX - a material with a standard specific gravity with hollow glass spheres in the composition, which improve its thermal insulation properties.
• ROYALPLAST - premium grade sheet with increased specific gravity, triple UV protection and increased impact resistance.
