Product description:
Specifications a non-hydrolytic foam stabilizer of polysiloxane polyether copolymer, with a silicon-carbon bond. Product Name: Rigid Foam Stabilizer Description: silicone stabilizer is a non-hydrolytic foam stabilizer of polysiloxane polyether copolymer, with a silicon-carbon bond. It is a new modified product which is mainly used in rigid foam of PU plastic. Typical data: ? Appearance: Light yellow to amber transparent liquid ? Content of active material: 100% ? Viscosity(25C): 600-1200 cp Features: ?silicone stabilizer has good solubility and stability in the premixed systems containing isocyanate, polyether polyol, blowing agent of fluorocarbon, water, catalyst of amine and organic tin, and fire retardant. ? silicone stabilizer can significantly reduce or even eliminate the ‘shear line’ phenomenon of plastic products, which helps to improve the insulation effect of refrigerators and freezers, and enhance the bonding strength of the foam and the refrigerator shell. ? Silibase-2891 is particularly suitable for the foam formulation of low fluoride, can reduce the amount of CFC-11 more than 50%. ? Because of the above advantages, silicone stabilizer is particular suitable for the production of premixed polyether used in insulation materials of refrigerators and freezer, laminations, insulation pipes and spray. How to use: Use levels of 2 to 3 parts silicone stabilizer per 100 parts polyols are suggested. The optimum dosage is determined by the particular foam formulation. Packaging and Storage: ? Available in 25 liter pail and 200 liter drums. ? 24 months in closed containers.
