Silicone rubber is generally used to contain unsaturated double bond silicone oil, plus filler by mixing and refining; silicone resin, is a big concept, from the use of silicone resin (or silicone oil) is the raw material for the manufacture of silicone rubber or plastic.
Silicone rubber, divided into hot vulcanization type (high temperature vulcanization silicone HTV), room temperature vulcanization type (RTV), of which the room temperature vulcanization type is divided into condensation reaction type and addition reaction type. High temperature silicone rubber is mainly used in the manufacture of a variety of silicone rubber products, while the room temperature silicone rubber is mainly used as an adhesive, potting materials or molds. Hot vulcanized type with the largest amount of hot vulcanized type and divided into methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, the amount and product grade most), methyl vinyl phenyl silicone rubber PVMQ (low temperature resistance, radiation resistance), and other eye-catching silicone rubber, fluoro-silicone rubber and so on.
Silicone resin, the scientific name of polysiloxane resin. It is a polyorganosiloxane with a highly cross-linked network structure, and has the dual characteristics of an organic resin and an inorganic material, and silicone resin has unique physical and chemical properties. Silicone resin, the scientific name of polysiloxane resin (English name: Silicone resin) is a highly cross-linked network structure of polyorganosiloxanes, both organic resins and inorganic materials with dual characteristics, silicone resins have unique physical and chemical properties.
