OH-Terminated polydimethylsiloxane,is usually colorless transparent viscous liquid typically can be used as the base polymer of silicone rubberby reacting with crosslinking agent and catalyst at room temperature.The cured silicone rubber can keep elasticity for a long time during -60~200℃. It is with excellent electrical properties and chemical stability, aging resistance, corrosion resistance, resistance to water and moisture, non-toxic, insulation, quake-proof, low shrinkage etc.
