Taking full advantage of the high insulation and heat resistance of methyl phenyl silicone resin, silicone molds were prepared by adding heat resistant insulation filler into the silicone resin, which can be used as heat resistant insulation packaging material or high insulation moisture-proof protection material for high-power electrical components. Considering ratio of organic silicon mold plastic products, economic applicable silicone molding compound with middle and low R/Si and low Ph/R silicone resin as base polymer, with quartz powder, chopped glass fiber, mica powder as filler, mixed plasticate, cooperate the curing agent, such as metal organic acid salt preparation of molding compound makings, transfer molding technology on processing of organic silicon mold plastic products.
Silicone foams are prepared by using silicone moulding plastics to replace expensive polyimide foams for high temperature resistant insulation and heat insulation materials. From cheap accessible methyl chlorosilane and phenyl chlorosilane monomer, first by hydrolytic condensation reaction of low R/Si system without solvent methyl phenyl silicone resin, add chopped glass fiber and hollow glass beads lightweight filler, cooperate proper foaming agent and curing agent, using transfer molding process, silicon resin curing reaction and mold plastic foaming synchronization carry on, Preparation of light and high strength heat resistant foam plastics
