Product Name: Rigid Foam Stabilizer
n Description
Silibase-2898 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 is suitable for the foam systems of all water, HCFC-141b and hydrocarbon, especially for HFC-365mfc/227ea.
n Typical Data
Ø Appearance: Light yellow to amber transparent liquid
Ø Content of active material: 100%
Ø Viscosity(25°C): 1000-2000 cp
n Features
Ø Silibase-2898 has a unique design of molecular structure, thus it has excellent emulsifying ability, nucleating and foam stability ability.
Ø Silibase-2898 has good solubility and stability in the premixed systems containing polyether polyol, water, amine catalyst and fire retardant etc., ensuring that the premixed polyether is transparent and the reaction fluidity is better, especially in the foam system of HFC-365mfc/227ea.
Ø Silibase-2898 can significantly reduce or even eliminate the ‘shear line’ phenomenon of plastic products, making foam structure more uniform, and close-cell rate higher. Thereby the insulation performance and mechanical strength are enhanced.
n How to use
Use levels of 1.5 to 2.5 parts Silibase-2898 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.
