Polyurethane Foam Polyether Polyol

Polyurethane (Pu) Foam Polyether Polyol For Rigid Foam
DESCRIPTION
LL 33H 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 to make rigid PU foam through PU spray machine. The foam produced has the characteristics as following:
 

1. The strong adhesive force, convenient construction and no seams.

2. The low thermal conductivity, low water absorption and good dimensional stability.

3. The long service life.
