Polyurethane foam is a material widely used in life. Mainly used in the building materials industry to bond and utilize the gaps between doors and windows. Therefore, the quality of foam rubber is particularly important. Poorly made polyurethane foam can cause damage to doors and windows soon after bonding. Therefore, it is very important to choose good styrofoam materials when decorating a house.
The editor below will teach you a few tips on how to distinguish “real and fake” styrofoam.
1. Look at the foam size. Good foam will have full and round foam; inferior foam will have less foam and collapse.
2. Cut the surface to see the cells. If the cells are uniform and fine, it is a good foam; if the cells are large and the density is not good, it is an inferior product.
3. Look at the adhesion, good foam Strong adhesion, bad foam has poor adhesion.
4. When playing with foam, spray it The foam should not be too thin or too thick. Too thin and the foam will collapse. If it’s too thick, the foam can easily dry and shrink.
5. Squeeze the foam block with your hands. Foam blocks have good dimensional stability. It will be elastic after complete curing. It is not good if it is too soft or too hard.
6. Judge by color. Good polyurethane foam will be milky white after curing. Neither white nor yellow looks good.
7. After using the product, shake it Shake the can, and good products will not get dirty.
