WynPUF® XH-1625 PU Rigid Foam stabilizer
Product Description:
WynPUF® XH-1625 foam stabilizer is a Si-C bond, non-hydrolytic type polysiloxane polyether copolymer. It is mainly suitable for rigid polyurethane foam with Pentane foaming system.
Physical data：
Appearance： clear liquid
Viscosity at 25℃：600-1200 cp
moisture：≤0.3%
PH (1% aqueous solution)：6.0±1.0
Applications:
Suitable for discontinuous /continuous panels,spray foam, pipe insulation system, specially designed for high-end refrigerators, refrigerators and other hard foam system.
It can provide fine cell structure, which makes the foam products have lower thermal conductivity.
It can provide high flow of foaming material, has good density distribution and strength distribution, and can reduce foam surface voids.
It can provide low K factor.
It can provide good insulation performance.
The common level range for XH-1625 is 2.0 to 3.0 parts per hundred of polyol.
Package and storage stability：
Available in 200kg drums. 24 months in closed containers
