Technical Data Sheet
Item No.: Silibase-2897
Product Name: Rigid Foam Stabilizer
n Description
Silibase-2897 is a polysiloxane polyether copolymer with silicon-carbon bond and non-hydrolytic type, which is suitable for all kinds of rigid systems of HCFC-141b, with excellent foam fluidity and coefficient of heat conductivity.
n Typical Data
Ø Appearance: Light yellow to amber transparent liquid
Ø Content of active material: 100％
Ø Viscosity(25°C): 500-1000 cp
n Features
Ø Because of excellent surface activity and emulsifying ability, Silibase-2897 enables the storage stability of the premixed polyether more desirable, foam structure more uniform, and close-cell rate higher. Thereby the insulation performance and mechanical strength are enhanced.
Ø Silibase-2897 is suitable for rigid foam and pour-in-place applications, with excellent fluidity.
n How to use
Use levels of 1.5 to 2.5 parts Silibase-2897 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.
