Discription:
Silibase-2895 Rigid Foam Stabilizer is a Si-C bond, non-hydrolytic type, polysiloxane polyether copolymer. This is a versatile foam stabilizer used for the production of polyurethane rigid foam plastic, and its field of application is very wide, for example, it can be used in foaming systems including iso-, cyclo pentane, HCFC-134a,141b and high water content foaming system.
Physical data：
Appearance：clear-straw liquid
Active content：100％
Viscosity at 25℃：600-1200cp
Moisture content (%) :<0.3%
Feature:
Because of the uniquely designed molecular struture of Silibase-2895 Rigid Foam Stabilizer, this gives the product a superior capacity in emulsifying, nucleus forming and foam stabilizing, thus, the fluidity of the foaming materials will become better, and an uniform density distribution of the molded finished product is ensured. Moreover, the foamed plastic material will have extremely small cell and narrow cell distribution, as well as a very high rate of closed cell.
Dosage (additive as supplied):
1-2% is recommended for preparing polyurethane rigid foam. Use levels for this type of foam can vary from 1 to 2 parts per 100 parts polyol.
Package and storage stability：
Available in 25 liter pail and 200 liter drums.
24 months in closed containers.
