The difference between foam caulking and foam glue

Simply put, foam rubber is a type of rubber. Also known as sponge rubber. Vulcanized rubber with a sponge-like porous structure. There are open pores, closed pores, mixed pores and micropores. Can be made into soft rubber or hard rubber products. Light, soft, elastic and not easy to conduct heat. It has the functions of shockproof, impact mitigation, heat insulation and sound insulation. Made of synthetic rubber, it is also resistant to oil and aging. It is widely used in automobiles, aircraft, chemicals, daily necessities and other industries as thermal insulation, sound insulation and shock-proof materials, as well as making seat cushions, mattresses, medical machinery, sanitary products, sporting goods, etc. It can be made by adding foaming agents (such as ammonium carbonate, urea, azobisisobutyronitrile, etc.) to raw rubber or concentrated latex, stirring and blowing air into it, and then vulcanizing.

Foam caulk is a It is a glue with foaming properties and bonding properties. It is mainly used for filling, sealing and bonding the side seams of building doors and windows, component expansion joints and holes. It is a polyurethane elastic sealing foam material that relies on moisture curing. Weigufoam caulking agent is to fill polyurethane prepolymer, foaming agent, catalyst, cross-linking agent, etc. into high-pressure iron cans in and filled with propane and other gases. It is divided into two types: gun type and tube type. The gun type requires a special polyurethane foam gun to use, and the tube type is equipped with a disposable hose. Value is the difference between the two, I hope it can help everyone.
