Project Description

IR-SYM

Application

IR-SYM is a kind of siloxane-ether copolymer with silicon-carbon structure.

IR-SYM is anti-hydrolysis and chemically stable. It mainly applies to rigid polyurethane foamed plastics.

Features

1. Excellent compatibility and stability in combination with polyether polyols;

2. Outstanding surface activity and emulsifying ability. Therefore, polyether polyol pre-mixed with IR-SYM has better storage stability, evener cell structure, and higher closed-cell rate. As a result, the heat-insulating property and mechanical strength of the foams are greatly enhanced.

3. IR-SYM gives materials good fluidity, even density distribution, and excellent foam stability. Then, a shear line can be minimized. It is the best foam stabilizer for fluorine-containing or fluorine-free premixed polyether polyol.

Other Silicone Surfactant for Rigid Foam

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.
