China Rigid Foam Stabilizer rigid foam CAS NO.68937-55-3

item no.: silibase-2895

product name: rigid foam stabilizer

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).

typical data

appearance: light yellow to amber transparent liquid

content of active material: 100％

viscosity(25°c): 500-1500 cp

features

silibase-2895 has a unique design of molecular structure, thus it has excellent emulsifying ability, nucleating and foam stability ability.

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.

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

packing and storage

available in 25 kg pail and 200kg drums.

24 months in closed containers.
