1. If it is a gun-type product, the quality of the gun can be judged from the effect of the gun. The sprayed foam should be uniform and smooth, not too large or too thin, and it should not collapse. It is not that the thicker the better, otherwise the foam will shrink and affect the effect.
2. Punch out the foaming agent, apply a layer, and see if there is any phenomenon of warping around the foam the next day? If there is no warping, it means the product is good.
3. Cut the beaten foam to see if the cells are uniform and fine? If the cells are large and the density is uneven, it means that it is not a good product.
4. Look at the surface of the foam, is it smooth and shiny? The gloss here is not shiny or wrinkled.
5. Look at the size of the foam. The foam of good quality is round and full, while the foam of poor quality is very small and will collapse.
6. Try it with your hand and feel the elasticity of the foam. A product that is flexible is a good product, and a product that is not flexible is of poor quality. In order to ensure the quality of products, it is best to cooperate with powerful suppliers.
7. Look at the adhesion of polyurethane foam insulation products. The better the quality of the product, the stronger the adhesion of the foam. This is the most basic performance.
Learn how to judge the quality of polyurethane foam insulation products so that they can be used with confidence in some environments. In general, the curing time of this product varies, and the drying time varies with the seasons. As long as it is completely dry, it can play a stronger role and will not affect normal use.
