Product Description

Product Description

Description
SY-Spray235 Our innovative blend of polyols combined with HCFC-141B as the blowing agent synergizes magnificently with isocyanate to create a foam that is renowned for its exceptional attributes:
1-fine and uniform cell structure, ensuring consistency and reliability
2- remarkably low thermal conductivity, optimizing energy efficiency
3-outstanding fire resistance that prioritizes safety
4- superior stability even in low temperature environments, enhancing durability.
Ideal for various thermal insulation applications,including cold storage rooms, expansive storage tanks, extensive pipelines, both external and internal wall insulation, as well as other spray insulation endeavors.
