Liquid Spray Pu Foam Blend Polyols for Wall Insulation
Blend Polyol SDA22D
Building Wall Spray Rigid PU Foam
DESCRIPTION
SDA22D building wall insulation system blend polyol is a kind of B2 grade spray rigid PU foam blend polyol, specially used for the insulation of building external wall. 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.
