The best mounting foams 2022
Polyurethane foam sealant, which is popularly called polyurethane foam, is a rather peculiar product. Choosing the most suitable one is not easy. KP has ranked the best polyurethane foams of 2022. In it, we analyzed in detail the features of each manufacturer.

Mounting foam was born relatively recently. Moreover, as is usually the case with interesting discoveries, it was invented by accident. This was succeeded by the German inventor Otto Bayer. The latter experimented in the laboratory with polyurethane. In the 70s of the last century, scientists managed to put this mixture into an aerosol can. This caused a wide demand for it in society. In Our Country, the first sales of polyurethane foam began in Moscow during the Soviet era. However, she soon began to appear in other cities of the country. Today, polyurethane foam is used for insulation, sound insulation, installation of door and window openings, as well as filling voids. Its principle of operation is quite simple. Initially, it is in a liquid state, but after spraying and due to contact with water and air, polyurethane is formed. Also, some use foam as a decoration. From it create sculptures, figurines and much more.

According to their characteristics, foams differ in composition, temperature of application, type of packaging, flammability class, scope and price. To understand all these details, we turned to construction YouTube channel blogger and master finisher Pavel Sidorik.

How to choose mounting foam

At the beginning of our material, we already said that there are several different parameters that you should be guided by when choosing a mounting foam. Now let’s look at them in more detail.

Adhesion

This is an indicator of the adhesion of dissimilar solid and liquid bodies. In our case, it indicates the ability of the foam to adhere to various materials. The higher the adhesion, the tighter it fits.

Outlet foam volume

This parameter indicates how many liters of foam will be obtained from one can. According to our expert, this is one of the most important indicators. Since by dividing the volume by the price, you can find out the actual cost of the product and compare manufacturers.

Primary and secondary expansion

Primary expansion indicates how much the foam will expand after being released from the can. It should not exceed 25% of the original volume. This will mean that you have purchased a really high-quality foam. Secondary expansion is how much the volume will increase after polymerization. This indicator is also of great importance, since the probability of deformation of the structure in which the product is used depends on it.

Winter, summer, all-weather foam

According to this indicator, it is possible to determine at what temperature it is necessary to apply mounting foam. So, summer hardens at temperatures from +5 to +35 degrees Celsius. The required moisture level for curing is reduced from 60% to 35%. Winter polyurethane foam can be used at temperatures up to -20 degrees Celsius. All-weather foam will work at any of the above temperatures.

Gun or plastic tube

All brands of polyurethane foam sealants can be divided into two types: professional and household. The latter are applied to the surface using plastic nozzles. As for professional ones, you need to purchase a special pistol for them.
