Product Description

Product Description

SY-C235 is a kind of blend polyols ,it reacts with isocyanate to produce foam which has good performances:
 1- good compressive strength and dimensional stability
 2- lhigh closed cell rate 
 3-good waterproof performance
 4- good heat insulation performance
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 insulation projects.
