Product Description
VS-3 Spray Blend Polyols for Closed Cell Foam
VS-3 spray blend polyols utilize 245fa blowing agent instead of HCFC-141B, reacting with isocyanate to produce foam with exceptional performance characteristics.
Key Performance Features
- Fine and uniform cell structure
- Low thermal conductivity for superior insulation
- Excellent flame resistance properties
- Good dimensional stability at low temperatures
Ideal for various thermal insulation applications using spray technology, including cold rooms, storage pots, and large-scale pipeline insulation.
