![What is conductive silicone rubber?]()
The conductive silicone rubber is based on silicone rubber, which is made by adding conductive filler and crosslinking agent. The commonly used materials are methyl vinyl silicone rubber. The commonly used conductive fillers are acetylene carbon black, carbon fiber, superconducting carbon black, graphite, copper powder, silver powder, aluminum powder and zinc powder.
Compared with general conductive rubber, conductive silicone rubber has the advantage of small volume resistivity, low hardness, resistance to high and low temperature (70-200 ℃), ageing resistance, processing and manufacturing process performance is good, especially suitable for manufacturing conductive performance is good, complex shape, the structure of tiny conductive silicone rubber products.
The characteristics of
It has the characteristics of high and low temperature resistance, aging resistance and easy forming process of ordinary silicone rubber, and it has good conductive stability and thermal stability.
Physical and chemical data
Volume resistivity is in commonly 3 ~ 10 Ω · cm, relative density 1.15, hardness 60 shaw (A), the tensile strength of 5.7 MPa, relative elongation is 265%. It can be mixed with methyl vinyl silicone rubber (raw rubber), white carbon black, conductive filler, structural control agent and organic peroxide.
use
Because the conductive silicone rubber has small size, stable and reliable contact, shock the advantages of good performance, convenient exchange, used for printed circuit, wireless integrated circuit, display, such as the connection between, can save a lot of welding work, simplifies assembly, smaller volume, lower the cost and improve the reliability.
The columns can be used for the connection between the conductive button, the conductive silicon rubber roller, the printed circuit and the integrated circuit and the display.
