VS-W01 PU Blend Polyols for Spray Foam
VS-W01 belongs to the spray blend polyols series with a pale yellow to brown yellow transparent liquid .After reacting with isocyanate at the certain ratio to produce foam. Mainly used in the building wall thermal insulation project, cold storage, tanks and large pipes etc. By in high (low) pressure spray foam machine. It have the advantage of smooth and uniformity cell fine thermal insulation , excellent low temperature dimentional stability and so on.
