Product Description
Polyols Blends and Isocyanate
Polyol blends react with isocyanate to form polyurethane(PU) foam, which has the characteristics of even and delicate foams, low thermal conductivity, good heat preservation and heat insulation, and high and low temperature stability.
Polyurethane foam is compatible with different kinds of coating. For example: concrete, fiberglass, gypsum board, etc.
