Product Description
SY-Spray235 blend polyols with HCFC-141B as blowing agent, it reacts with isocyanate to produce foam which has good performances:
1-fine and uniformity cells
2- low thermal conductivity
3-perfect fire resistance
4- excellent low temperature dimensional stability.
Suitable for all kinds of thermal insulation projects,such as cold room, large tank, large pipeline, external wall or internal wall and other use of spray insulation projects.
