Many people do not know polyurethane foam insulation materials, do not know how to use? It has been proved that this material has various properties and can play a role in different environments.

As long as it is used in the right situation, it can play a super effect and resist all kinds of bad environment.

How to judge the quality of polyurethane foam insulation?

1. If it is a gun type product, we can judge whether it is good or bad from the gun effect. The foam should be smooth and smooth, neither too big nor too thin. The thicker the better, otherwise the foam will shrink and affect the effect.

2. Blow out the foaming agent and look at it for the next day. If there is no warpage, the product is good.

3. Open up a good bubble to see if the cell is even and delicate. If the cell density is very large and uneven, it is not a good product.

4, look at the surface of the foam, is it smooth and glossy? The luster here is not shiny or wrinkled.

5, look at the size of the foam, the quality of the foam is round and full, the poor quality of the bubble is very small, there will be collapse.

6, try it with your hand and feel the elasticity of the foam. Good products are full of elasticity, but those without elasticity are of poor quality. In order to ensure the quality of the products, it is better to cooperate with the powerful suppliers.

7, look at the adhesion of polyurethane foam insulation products, the better quality products, the stronger the adhesion of foam, this is the most basic performance.

Learn how to judge the quality of polyurethane foam insulation products, in order to use safely in some environments. Generally speaking, the curing time of the product is different, and with the change of seasons, the dry curing time is also different. As long as it is completely dry and solid, it can play a stronger role without affecting normal use.
