Solar protection
Renewable solar energy is one of the fastest growing industries today. The specificity of the operation of solar panels provides for a constant, maximum possible exposure to the entire spectrum of sunlight. At the same time, the most advantageous arrangement of the modules is low-cloud sandy deserts with an abrasive nature of the effect of winds and storms. To protect solar cell modules from both the front and back surfaces, ETFE films with a thickness of 25 µm or more are used. Compared to ETFE glass, the films are more transparent and incomparably lighter, which reduces installation and logistics costs, as well as contributes to the safe execution of coating work. ETFE protective barrier films compete very well in this application with a wide range of plastics used: polyvinyl fluoride (PVF), PVDF, PET and others. Recently, ETFE films have often been used in combination with other polymer layers such as PET and / or ethylene vinyl acetate (EVA), which improves electrical breakdown resistance and interlayer adhesion, resulting in a highly competitive product. The surface micro-lenticular modification ETFE is capable of imparting anti-glare to the film, which additionally increases the collection of solar energy by the PV modules of buildings. In some cases, ETFE film encapsulates, along with solar cells, inverters - LED and OLED elements used in the concept of building smart homes and autonomous facades.
The flexibility of ETFE protection facilitates the creation of portable photovoltaic converters capable of powering various gadgets or specialized portable electronics.

A bit of history
The discoverer of Teflon is the American scientist Roy Plunkett, who in 1938, as an employee of Kinetic Chemicals, witnessed the polymerization of gaseous tetrafluoroethylene and its transformation into a solid substance resembling paraffin. The resulting material showed amazing properties at that time, so it was immediately registered as a development of the Kinetic Chemicals company, which in 1949 became part of the DuPont corporation.
Teflon first came to the Soviet Union during the Second World War. The teflon ring was part of the design of the turret rotation system for American-made tanks that came to the USSR under Lend-Lease. The Soviet designers were impressed by the fact that instead of lubricant, a fluoroplastic gasket was used to rotate the turret of a foreign tank. After getting acquainted with the technical characteristics of the material, it was decided to establish its own production. For a long time, the use of fluoroplastic in industry, as well as the technology of its production in the Soviet Union, were classified.
Application of F-40 (ETFE) films
A very significant place in the sales of ETFE films is explained by a wide range of purposes and a number of technical advantages over conventional films, glass and polycarbonate sheets. Film manufacturers offer a variety of ETFE grades, differing in thickness, surface finish and additives for the following applications:
- Architecture;
- Agricultural and greenhouse applications;
- Solar panels protection;
- Electronics: printed circuit boards and semiconductors;
- Construction: interior decoration of premises;
- Industry: cable tape insulation;
- Medical industry.

Features of PTFE film
The PTFE web is presented in the form of a translucent or matte white material. It is a polymer product, chemical formula - PTFE (polytetrafluoroethylene). Often referred to as Teflon sheeting.
The polymer is produced by extrusion. A workpiece is made of fluoroplastic powder. It is also called a pill. Then the top layer is removed from it, which is rolled through the rollers to the required size. The resulting material is cut to the desired width and wound onto spools.
Fluoroplastic sticky oil-resistant film is supplied to consumers in rolls of various lengths:
- 50 meters;
- 100 meters;
- 250 meters.
Has a thickness of 0.005 to 0.1 mm. The width of the fabric made of fluoroplastic f 4d can be from 10 mm to 120 mm. Strength and elasticity are distinguished from the quality characteristics.
The fluoroplastic polymer complies with safety and environmental requirements: it does not burn, does not explode, does not require special conditions during its processing and storage.
Shows excellent performance when working in aggressive environments.
The shelf life of the material is 20 years.
Greenhouse and greenhouse construction
The most widespread greenhouse coverings in the world are polymer films: Southern Europe, Arab countries. Greenhouse complexes in Israel and North. Africa occupies 190,000 hectares; of which 168,000 hectares are covered with polymer films; the other part is glass or polymer sheets. In Asian countries, the area of greenhouses is ~ 380,000 ha - China, 60,000 ha - Japan and 2,200 ha Korea. The coverage of these greenhouses is almost 100% - polymer films. Russia today is ~ 60% dependent on the import of greenhouse vegetables (China, Turkey). Now the country has about 1900 hectares of greenhouses and the pace of their construction is low. The use of modern ETFE material in greenhouse and greenhouse business is hindered by the high cost per square meter, reaching 1080 rubles with an optimal thickness of 100 microns. Nevertheless, Tander CJSC, which has its own sales system - a chain of food stores “Magnit”, has built the most modern greenhouse complex LLC “Greenhouse complex“ Green Line ”with an area of 90 hectares using the Japanese ETFE F-Clean film! The choice of covering material was facilitated by a significant increase in the yield of vegetable crops and savings on metal structures.
Wide range of climatic conditions
Greenhouses using ETFE have already proven their worth in the Far North.On the other hand, the material is successfully used in the construction of buildings in the hot conditions of deserts and humid tropical climates.
Transparency in the visible and UV spectra
Glass and polyethylene transmit only 5% of the solar spectrum necessary for the plant. The maximum transparency of ETFE is 95%, and in the ultraviolet range it is over 90%. Full spectrum light, especially UV-A, plays an important role in plant health. In the natural environment, under the influence of ultraviolet radiation, the plant produces a greater amount of protective biologically active compounds - beta-carotene, anthocyanins and glycosides. They provide color, flavor and nutritional value to plants. In addition, ultraviolet light inhibits the development of many microorganisms, including fungi and bacteria that cause plant diseases in greenhouses. The main consequence of the higher transparency of ETFE films in greenhouses is undoubtedly the taste of vegetables and fruits in open field!
Durability
In traditional film greenhouses, the film has to be replaced every 3-5 years, since its light transmittance and strength characteristics decrease as a result of aging. The test results show that the light transmittance of ETFE film decreases by only 5% after 20 years of use with a warranty of more than 30 years. In the aging tests carried out by Dyneon, after 10 thousand hours of exposure to UV radiation (Xenontest 150 test), no signs of optical damage to ETFE were detected. In this regard, the Japanese firm AGC estimates the beginning of the destruction of the carbon chain to be over a hundred years.
Maintainability
In case of mechanical damage to the film with a sharp object or bird's beak, it can be easily repaired with a special tape made on the basis of the same film.
Anti-drop effect
It consists in the absence of the formation of condensate drops on the surface of a specially treated film, capable of falling on plants (one of the reasons for the disease of seedlings with powdery mildew).
Self-cleaning greenhouses
The high strength of the material in combination with the optimal angle of inclination of the roof and the surface anti-adhesive effect does not allow the accumulation of sediments. The material is also not damaged by hail. Dirt, foliage, pollen and dust slide off ETFE better than other plastics. Dirt-repellent properties depend on the value of the surface tension of the material, the lower it is, the more anti-adhesive surface. The range of surface tension reduction is as follows: polyamide (PA) polyethylene terephthalate (PET), polyetheretherketone (PEEK), polyethylene (PE), polyvinylidene fluoride (PVDF), fluoroplast-40 (ETFE), fluoroplast-4 (PTFE).

Due to the increased fire resistance, chemical resistance,
excellent electrical and mechanical performance over a wide range
temperatures, films made of fluoropolymers have also found application in areas
making increased demands on reliability, durability,
fire safety. Such requirements, in particular, exist in
aviation and space industries.
Our achievements in the production of fluoroplastic films
In the production of fluoroplastic (f-4) films, there has always been a problem of obtaining ultra-thin and wide films. Until now, TU 6-11-5751766-1-88 operates according to which the maximum width of film materials with a thickness of 0.04 mm and more does not exceed 290 mm. In this case, gouging technology is used without subsequent orientation, which significantly affects the physical and mechanical properties of such films for the worse. According to foreign data, non-oriented films from F-4 with a thickness of 0.1 mm are planed with a width of up to 500 mm, and with a thickness of 0.2 mm and up to 1500 mm. At the same time, unique equipment for gouging and special equipment for hydro-compacting of workpieces of large length and diameter is used.
We also carry out chemical activation of the surface of a fluoroplastic film made of F4, F4K20
Chemical activation of the film surface allows the fluoroplastic to be glued to other surfaces. It is not possible to glue fluoroplastic without chemical activation.
Surface-activated fluoroplastic film:
What it is?
PTFE film is an extruded polymer material. Fluoroplastic powder is used as a base. A blank is made of it, in professional slang it is called a "pill". The technological process involves careful monitoring of the homogeneity of the material. According to state standards, not the slightest sign of impregnation of foreign substances is allowed.
The film has high strength, elasticity and resistance to aggressive environments. In the manufacturing process, the technology of the cold method is used. Wide shavings, similar to long strips, are cut from the blanks and rolled. This reduces the thickness of the belts, gives the material strength in length and width. Then the film is rolled into rolls. A similar method is used to produce fluoroplastic tape.

Areas in which fluoroplastic is used
Today Teflon is used in almost all areas of economic activity. It is actively used in medicine, pharmaceuticals, energy and construction, automobile and aircraft structures. The use of fluoroplastic in the food industry is widespread. Fillers for high-temperature membrane filters, heat-resistant gaskets of various types, critical elements of shut-off and control valves, valves and pumping equipment in the chemical industry are made from it.
Machines and mechanisms
The structural properties of Teflon are used in the production of vehicles, machines, mechanisms, in machine tool building and the aviation industry. In units subject to high loads, sliding elements and bearings are used, consisting of a metal base covered with Teflon.
During the operation of the mechanism, the fluoroplastic leaves a thin film on the surface with which it comes into contact, due to which it is possible to significantly reduce the coefficient of friction.
For the same reason, finely dispersed fluoroplastic is sometimes added to the composition of lubricants. A thin layer of Teflon coating that forms on the rubbing surfaces of the elements during operation allows the mechanism to continue to work for some time if the lubricant for some reason has ceased to flow into the system. In addition, Teflon glands and sealing elements are a must in high pressure piping and hydraulic systems in most machine designs.
Medicine and pharmaceuticals
PTFE has good compatibility with the human body, therefore it is successfully used for the manufacture of prostheses in surgery, cardiology and dentistry. Artificial substitutes for blood vessels of the circulatory system and heart valves are made from fluoroplastic. Now Teflon has replaced titanium, the use of which for the manufacture of prostheses previously imposed a number of restrictions on human life.
Food industry
The use of fluoroplastic in the food industry is also noteworthy. It is used as an inner liner for pipelines and for stuffing box seals in pumps handling various raw liquids such as sunflower oil, lecithin, fat and dairy masses.
Non-stick coatings for cooking containers are also made of Teflon.
The Tefal cookware with a non-stick surface has become very popular.
Chemistry
In the chemical industry, the use of fluoroplastic is widespread for the manufacture of parts for shut-off and control valves and sealing elements of vessels and pipelines transporting liquid solutions with a high degree of chemical aggression. Due to its ability to withstand the effects of chemically active substances, the material is used in column-type reactors, extractors and various containers as a lining for surfaces in contact with an aggressive medium.
electrical and Electronics
In electrical engineering, instrument making and electronics, fluoroplastic is used as a dielectric.Teflon sheeting is an essential component of today's high quality cable products. Insulating fluoroplastic materials are used for the production of coils, capacitors and boards. PTFE insulation is able to withstand the effects of high-temperature corrosive environments.
Construction
Fluoroplastic plates are the most important parts of the structures of sliding supports of critical structures, such as bridges, galleries, overpasses, overpasses and other spans. In regions with a high level of seismic activity, Teflon gaskets are used in the places where the floor beams rest on the columns, as well as in the nodes for installing the columns on the foundations in order to ensure the possibility of free movement of the building frame elements of the building frame.
Manufacture of clothing and specialty fabrics
The thinnest film that forms during the deformation of Teflon raw materials serves as a coating for special types of fabric.
This fabric is used for sewing high-tech clothing with water-repellent and windproof properties.
At the same time, the porous material does not trap the natural vapors of the human body. Most modern sports and outdoor clothing has a thin Teflon coating.
