Thermal conductive silica gel, also known as thermal conductive silicone rubber, thermal conductive silicon rubber, thermal conductive silicon likon, etc. It is made of organic silica gel as the main body, adding polymer materials such as filling material and thermal conductivity material, and has good thermal conductivity and electrical insulation performance.

Thermal conductive silica gel includes room temperature vulcanization and high temperature vulcanization, which is mainly used for elastic bonding, heat dissipation, insulation and sealing of 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). Usually, the thermal conductivity of high temperature vulcanized thermal silica gel is higher than that of room temperature vulcanized, high temperature vulcanized thermal silica gel is mainly used in the form of pieces, as gaskets or heat sink; RTV thermal conductive silica gel is mainly used for bonding and packaging of heat dissipation components in electronics, home appliances and other industries.

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