high quality foam stabilizer Silicone oil CGY-2 for polyurethane

Product description
CGY-1 is a polysiloxane - polyether copolymers, the strain silicon carbon structure, foam stabilizers hydrolysis, chemical stability, suitable for semi-rigid, rigid polyurethane foam is mainly used for pipe insulation, sandwich plates, spraying, enables the material has good fluidity, has an excellent emulsifying ability and surface activity, lowering the surface tension, and is formed to help nucleate bubble formation, storage stability of the composition can polyether more preferably, the other components of the system have a good compatibility, a long-term storage without separation due, CGY-1 can make the plastic more uniform cell structure, high closed porosity, thereby increasing the thermal insulation foam and mechanical strength.
