Product Description
VS-3 245fa Blowing Agent Blend Polyols
VS-3 spray blend polyols utilize 245fa blowing agent as an environmentally friendly alternative to HCFC-141B. When reacted with isocyanate, it produces high-performance polyurethane foam with exceptional thermal insulation properties.
Key Performance Features
- Fine and uniform cell structure
- Low thermal conductivity for superior insulation
- Excellent flame resistance properties
- Good dimensional stability at low temperatures
Applications
Ideal for thermal insulation engineering using spray technology, including cold rooms, storage tanks, and large-scale pipeline insulation systems.
