Thermal conductive silicone, also known as thermal conductive adhesive, thermal conductive silicone rubber, thermal conductive silicone adhesive, thermal conductive silicone, etc. It is made of organic silica gel as the main body, and polymer materials such as fillers and heat conduction materials are added. It has good heat conduction and electrical insulation properties.

Thermal conductive silica gel includes those vulcanized at room temperature and those vulcanized at high temperature. It is mainly used for elastic bonding, heat dissipation, insulation and sealing in the electronics, electrical appliances, instruments and other industries (it can provide the high elasticity and heat resistance required by the system, and can quickly transfer the heat of the system). Generally, the thermal conductivity of high-temperature vulcanized thermal conductive silica gel is higher than that of room temperature vulcanized thermal conductive silica gel. The high-temperature vulcanized thermal conductive silica gel is mainly used in the form of sheet, as a gasket or radiator; Room temperature vulcanized thermal conductive silica gel is mainly used for bonding and packaging of heat dissipation components in electronics, household appliances and other industries.

As a silicone rubber matrix with excellent insulation and shock absorption properties, its thermal conductivity is only about 0.2W/(mK). However, its thermal conductivity can be improved several times or even dozens of times by adding high-performance thermal conductive fillers, including metal fillers (such as Al, Cu, MgO, AIN, BN) and non-metallic materials (such as SiC, graphite, carbon black, etc.). The thermal conductivity of thermal conductive silicone materials is ultimately determined by the silicone rubber matrix, filler performance, filler proportion, filler distribution, processing technology, etc.
