Blend Polyol for Closed Cell PU Chemical Spray Foam Building Material
SDA33D building wall insulation system blend polyol is a kind of spray rigid PU foam blend polyol, specially used for the insulation of building roof. It used together with isocyanate(PM-200) to make rigid PU foam through PU spray machine. The foam produced has the characteristics as following:
- The strong adhesive force, convenient construction and no seams.
- The low thermal conductivity, low water absorption and good dimensional stability.
- The long service life.
