Product Description

Product Description

Description
SY-Spray235 The innovative SY-Spray235 combines superior blend polyols with HCFC-141B as a cutting-edge blowing agent. This powerful combination reacts seamlessly with isocyanate to create high-performance foam with remarkable attributes. Noteworthy features:
1-fine and consistent cell structure
2- exceptionally low thermal conductivity
3-outstanding fire resistance
4- superior dimensional stability even at low temperatures.
Perfectly designed for a wide range of thermal insulation projects, including cold rooms, large tanks, extensive pipelines, external and internal walls, as well as various other spray insulation applications.
