Product Description

Polyurethane Spray Blend Polyols 
VS-3  is spray blend polyols, blowing agent is 245fa instead of HCFC-141B, 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.
