China Rigid Foam Stabilizer silicone stabilizer CAS NO.9082-00-2

item no.: silibase-2897

product name: rigid foam stabilizer

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.

typical data

appearance: light yellow to amber transparent liquid

content of active material: 100％

viscosity(25°c): 500-1000 cp

features

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.

silibase-2897 is suitable for rigid foam and pour-in-place applications, with excellent fluidity.

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.

packing and storage

available in 25 kg pail and 200kg drums.

24 months in closed containers.
