IR-SY-1 for Rigid Foam
IR-SY-1 is a kind of siloxane-ether copolymer with silicon-carbon structure. It is anti-hydrolysis and chemically stable. It applies to rigid and semi-rigid polyurethane foamed plastics and mainly used in piping insulation, laminated board, and spraying.
IR-SY-1 gives the material good liquidity, excellent surface activity, and emulsifying ability. Moreover, it reduces the surface tension and then helps bubble nuclear and bubbles to form. Thus, it improves the storage stability of combined polyether and its compatibility with other components in the system.
A separation will not happen during long-term storage, IR-SY-1 also could even plastic bubble structure and increase the rate of the closed pore, so as to improve the foam insulation and mechanical strength.
IR-SY-5 for Rigid Foam
IR-SY-5 is a kind of siloxane-ether copolymer with silicone-carbon structure. It is anti-hydrolysis and chemically stable. It applies to rigid and semi-rigid polyurethane foamed plastic and mainly used in polyurethane component for refrigerator, door, and others.
IR-SY-5 gives the material good liquidity and reduces surface tension between molecules, thus stabilizing and uniforming the bubble hole.
