Rigid Foam Stabilizer
Silibase-2895 is a polysiloxane polyether copolymer with silicon-carbon bond and non-hydrolytic type, commonly used as a broad-spectrum foam stabilizer for rigid polyurethane foam. It has a wide range of applications, suitable for the foam system of high water content, HCFC-141b, HFC-134a, and hydrocarbons (eg. cyclopentane).
Technical Data Sheet
Item No.: Silibase-2895
Product Name: Rigid Foam Stabilizer
n Description
Silibase-2895 is a polysiloxane polyether copolymer with silicon-carbon bond and non-hydrolytic type, commonly used as a broad-spectrum foam stabilizer for rigid polyurethane foam. It has a wide range of applications, suitable for the foam system of high water content, HCFC-141b, HFC-134a, and hydrocarbons (eg. cyclopentane).
n Typical Data
Ø Appearance: Light yellow to amber transparent liquid
Ø Content of active material: 100%
Ø Viscosity(25°C): 500-1500 cp
n Features
Ø Silibase-2895 has a unique design of molecular structure, thus it has excellent emulsifying ability, nucleating and foam stability ability.
Ø Silibase-2895 allows the material fluidity more desirable to ensure uniform density distribution of the molded products, and allows the foam to have a very fine cell and narrow pore size distribution.
n How to use
Use levels of 1.5 to 2.5 parts Silibase-2895 per 100 parts polyols are suggested. The optimum dosage is determined by the particular foam formulation.
n Packing and Storage
Ø Available in 25 kg pail and 200kg drums.
Ø 24 months in closed containers.
