What is the conductive silicone rubber?

Conductive silicone rubber is made of silicone rubber as the base rubber, adding conductive fillers, cross-linking agents, etc., and vulcanized. The commonly used rubber is methyl vinyl silicone rubber, and the commonly used conductive fillers include acetylene carbon black, carbon fiber, superconducting carbon black, graphite, copper powder, silver powder, aluminum powder and zinc powder.

Compared with general conductive silicone rubber, conductive silicone rubber has the advantages of small volume resistivity, low hardness, high and low temperature resistance, aging resistance, and good processing performance. It is especially suitable for the manufacture of conductive silicon rubber with good conductivity, complex shape and fine structure. rubber products.

Because conductive silicone rubber has the advantages of small size, stable and reliable contact, good shockproof performance, and convenient replacement, it is used for the connection between printed circuits, radio integrated circuits, displays, etc., which can save a lot of welding labor and simplify assembly. The size is reduced, the cost is reduced, and the reliability is improved.

The newly developed conductive silicone rubber technology is bound to have a profound impact on the future market development pattern. From the perspective of the global conductive silicone rubber market, its future development trends mainly include the following aspects:

(1) Improve electrical conductivity while reducing filler loading;

(2) On the premise of improving the conductivity, maintain and improve the molding processability, mechanical properties and other properties of conductive silicone rubber;

(3) Develop new varieties of conductive materials and broaden the application fields.

Technically speaking, the replacement of metal materials by polymer materials is the development trend in the field of materials science in the future. As a result, the market demand for conductive polymers, that is, conductive silicone rubber, is increasing day by day, and its application fields are gradually expanding, which inevitably puts forward higher requirements for conductive polymers.
