Preparation and Characterization of Functionzliaed Silicone Oil for High Temperature Mold Release Agent

“…Methyl silicone oil has excellent electrical insulation, weather resistance, physiological inertness and low surface tension, but also has a low viscosity-temperature coefficient, high compression resistance [1][2][3][4][5]. However, there are certain disadvantages: poor compatibility of methyl silicone oil with organic materials and additives, heat resistance is not prominent enough, limiting its further application, for these defects, for silicone oil modification, alkyl functionalized silicone oil is obtained from methyl silicone oil in part of the methyl by the olefinic double bond and phenyl substitution, and other common silicone oil, compared with the advantages of high and low temperature resistance, and lubrication and irradiation resistance is excellent.…”
