Japan Bridgestone develops nonfron water foam polyurethane insulation

Japan's Bridgestone nonfron rigid polyurethane insulation is a product that uses an exclusive water foaming technology to solve problems such as construction and shape stability of non-fluorine cold blown insulation materials. The rigid PU foam heat insulation material uses the direct blow foaming method. Even if it is a complex shape, it can be applied in a short time and has excellent heat insulation. Therefore, it can be used in apartments, office walls, refrigerators, and freezers. At present, it is building a stadium for the university. In order to worry about the global environment, the company does not use fluorine-containing refrigerant gas, but instead uses "Everlite NFR," which was developed in 1999. The water foaming technology uses water and special isocyanic acid to produce carbon dioxide gas and then PU foams. , Special polyol with high activity and special isocyanate, can improve workability, shape stability, etc. by maintaining the special additives with low viscosity.
