VS-W03 Rigid PU Blend Polyols for Spray Insulation
Introduction
VS-W03 is spray blend polyols, blowing agent is 245fa, it reacts with isocyanate to produce
foam which has excellent performances, which are as follows,
1) Fine and uniformity cells
2) Low thermal conductivity
3) Perfect flame resistance
4) Good low temperature dimensional stability.
It applies to all kinds of thermal insulation engineering which uses the spray technology,such
as cold rooms, pots, large-scale pipelines etc.
