Features Hydroxy silicone oil is made by polymerization of siloxane monomers, the molecular silicone materials have hydroxyl groups at both ends. The structural formula:HO-Si (CH3) 2 O [Si (CH3) 2 O] n Si(CH3)2-OH Chemical name is a, w- dihydroxy polydimethylsiloxane, it name 107 silicone rubber when the viscosity is above 2500mPa.S. In addition to the general performance of methyl silicone oil, it also has reactive hydroxyl groups, it can be made available some new material or crosslinked into elastomers (or membrane) . Colorless transparent liquid with excellent electrical insulating properties and resistance to high temperature, high flash point, low freezing point, long-term used -50 o C ~ +250 o C conditions, low the viscosity-temperature coefficient, high compression ratio, low surface tension, hydrophobic moisture resistance, chemical inertness, physiologically inertness. Product Properties: Appearance : colorless transparent liquid. Viscosity (25oC, mpa.s): 25~100000 (can be customized) Hydroxyl content (%): 0.5 - 3 (related to the viscosity).
