Conductant silicon rubber is a base glue with silicone rubber, adding a conductive filler, a crosslinking agent, and the like. Commonly used compounds are methyl ethylene silicone rubber, commonly used conductive fillers include acetylene carbon black, carbon fiber, superconducting carbon black, graphite, copper powder, silver powder, aluminum powder and zinc powder.
Compared to general conductive rubber, the advantages of conductive silicon rubber are small in volume resistivity, low hardness, high low temperature (-70 to 200 ° C), aging, processing and manufacturing process performance, particularly suitable Conductive silicone rubber products having good conductive conductivity, complex shape and small structures.
has a high temperature resistance, aging resistance, an aging resistance, and the pharmaceutically acceptability, and good thermal stability.

Volume resistivity is generally at 3 to 10 Ω · cm, relative density 1.15, hardness (Shaofa A) 60, tensile strength 5.7MPa, relative elongation 265 %. It can be formed by mixing with methyl vinyl silicone rubber (raw glue), white carbon black, conductive filler, structural control agent, and organic peroxide.
Since the conductive silicone rubber has the advantages of small volume, stable and reliable contact, good shock resistance, convenient conversion, etc., for printed circuits, radio integrated circuits, displays, etc. Connection, you can save a lot of welding labor, simplify assembly, reduced the volume, and reduce costs, and improve reliability.
, for example, a connection between a conductive key button, a conductive silicone rubber roller, a printed circuit, and an integrated circuit, and a display.
