Profflex polyurethane foam: pros and cons

Advantages and disadvantages

Any building material has its own advantages and disadvantages, therefore, before buying foam, you need to familiarize yourself with all its properties and characteristics, study all the pros and cons of the material.

Profflex polyurethane foam has the following advantages:

• a high degree of adhesion (the foam can be used when working with coatings of stone, metal, concrete, wood, plastic and glass);
• fire resistance (foam does not conduct electric current);
• durability;
• fast setting time (the material dries completely in 3-4 hours);

• lack of a poisonous smell;
• affordable price segment;
• low porosity;
• high degree of sound / heat insulation;
• increased water resistance;
• ease of use.

If we talk about the shortcomings, then these include:

• Lack of UV protection. Under the influence of sunlight, the foam changes color - it darkens, it also becomes fragile.
• Fear of changes in temperature and humidity.
• Harmful to human skin, therefore it is necessary to work with the material only with protective gloves.

Analyzing all the pros and cons of a building material, it is worth noting that the material is endowed with many advantages, so you can use it without fear of negative consequences.

Views

The entire range of Profflex polyurethane foam is divided into two types: professional and household sealant. You need to choose one or another type depending on how much work is to be done using this material.

Polyurethane foam can be divided into types according to several characteristics.

• Composition. The mounting material can be one-piece or two-piece.
• Temperature conditions. Foam is produced for use in summer (summer), winter (winter) or all year round (all-season).
• Application method. Professional installation material is used with a pistol, while household material is equipped with a self-contained valve and a direction tube.
• Flammability class. Foam can be combustible, refractory or completely flame retardant.

The main difference between winter foam and summer foam is that there are special additives in winter assembly materials that help to increase the polymerization rate of the composition at negative and zero temperatures.

Each type of installation material has its own characteristics, its own scope and composition. To understand what type of foam is needed, you need to familiarize yourself in detail with the features of the main categories of Profflex materials.

Peculiarities

Polyurethane foam is a type of polyurethane sealant that contains the main and additional components. The main constituents are polyol and isocyanate. The additional ones include stabilizing and catalyzing agents, foaming agents.

Profflex manufactures one-component polyurethane sealants available in aerosol cans. The materials are easy to use: by holding the button on the dispensing gun or spray can, the mass is pushed out. Further, the foam expands, due to which the filling of air voids and cracks is ensured. When exposed to ambient moisture, the mass polymerizes.

The curing process of the material is directly dependent on humidity. The higher it is, the less time it will take for the sealant to harden. Because of this feature, experts recommend moistening the work surface with water before applying the composition.

Profflex manufactures and markets an extensive line of polyurethane foams. They can be used in different conditions, have different properties or differ in the method of application.

Range

Profflex is a polyurethane foam manufacturer that produces sealants for various types of work. The product range is extensive.

Consider the most popular materials for construction and repair work.

• Firestop 65. Fire-resistant, professional, one-component composition designed to seal air gaps in facilities where increased fire safety requirements are imposed. All-season sealant is used at both positive and negative temperatures. Possesses high adhesion. The initial polymerization time is at least 10 minutes.
• Fire Block OL. Fireproof sealant for professional use. The material is capable of not melting or burning when exposed to fire for 240 minutes. The one-component composition of FireBlock belongs to the all-season class, due to which it does not change its qualities when used in conditions of subzero temperatures and low air humidity.

• Pro Red Plus Winter. One-component winter material used at temperatures from -18 to 35 degrees. Foam has found wide application in the installation of doors and windows, filling voids, cracks and joints. It can be used as a heat or sound insulator. The output of the finished mass from 1 cylinder is about 65 liters.
• Storm Gun 70. Industrial compound with an output of 70 liters. Material contains a flame retardant substance.It is used only at positive temperatures. Differs in high adhesion to most materials. Can be used at low air humidity. Complete polymerization of the composition occurs 12 hours after application.

Advantages and disadvantages

Polyurethane foams produced by Profflex are high-quality materials that have both their advantages and disadvantages that must be studied before purchasing them.

Let's first list all the advantages of the sealant.

• High levels of adhesion to stone, concrete, wood, metal, glass, plastic and other types of surfaces.
• Fire resistance. This property is due to the material's ability not to conduct electric current.
• Fast polymerization of the applied mass. Basically, it will take 3-7 hours to completely dry the foamy mass. The time may be increased due to low humidity or freezing temperatures.
• No pungent odor.

• Reduced porosity.
• Resistant to moisture.
• Ease of use. Even an unprepared person can use polyurethane foam.
• Affordable price segment.

Polyurethane foams are not ideal material. Like all products for repair and construction, they have some disadvantages. One of the disadvantages is the fear of ultraviolet radiation. When exposed to the sun, the polymerized sealant changes color and begins to crumble, which leads to a loss of seam tightness. And also the applied foam can collapse during sudden temperature changes.

In addition to the above, the disadvantages include the harmfulness of polyurethane foam.
