1. The principle of styrofoam.

One-component polyurethane foam caulking glue is a new, environmentally friendly (Freon-free) and energy-saving building material. It is a special polyurethane product that fills polyurethane prepolymer, foam rubber, catalyst and other components into a pressure-resistant aerosol can. When the material is sprayed from the aerosol can, the foamy polyurethane material will rapidly expand and solidify with air or moisture in the matrix in contact to form foam.

2. Advantages of styrofoam.

Foam rubber is now used in many industries, so its advantages are self-evident in our lives, so let’s talk about foaming below. What are the specific advantages of glue

1 , The filling of styrofoam is important for The thermal insulation or cold insulation performance of the house is much better than that of cement mortar

2 , Nowadays, many people are troubled by the poor sound insulation effect of their houses. However, styrofoam has a certain sound insulation effect, so it is necessary to fill the cracks in the house. When caulking doors and windows, you can try to use Weigu foam glue

4Foam glue, as the name suggests, is an adhesive we use in our lives, so the adhesiveness of the foaming agent is an important point that many construction parties consider, and Wei Styrofoam is undoubtedly the leader among foam products.

5, Because foam rubber has a relatively high density, its sealing and moisture-proof performance is also relatively good.

6, Compared with cement mortar, styrofoam is much more convenient to operate than cement mortar and does not require cumbersome proportioning. The operation time of styrofoam is relatively short, saving manpower.�.

7, The anti-aging ability of foam rubber is also much better than that of cement mortar, and it is not prone to cracking and other phenomena.

8, Weigu foam rubber has very good self-extinguishing performance in case of fire (B1, B2 products).

There are many manufacturers of styrofoam on the market now, The quality of styrofoam is also uneven, but when we choose styrofoam, we must not be greedy for cheap. We must compare prices when the quality is the same. Don’t blindly pursue low prices.
