Conductive silicone rubber is made by mixing and vulcanizing silicone rubber with conductive filler and crosslinking agent. The commonly used rubber material 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.
        According to different base rubber varieties and processing methods, high-temperature vulcanized conductive silicone rubber and room temperature vulcanized conductive silicone rubber, as well as pressure-sensitive conductive silicone rubber, anisotropic conductive silicone rubber, and low-temperature conductive silicone rubber can be made.
        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 manufacturing conductive silicon with good conductivity, complex shapes and fine structures. rubber products.
        In recent years, the rapid development of electronic technology and instrument industry has promoted the improvement and development of conductive silicone rubber, and many new processes and varieties have emerged. For example, in the vulcanization process, the normal pressure hot air vulcanization of conductive silicone rubber has replaced the traditional high-temperature vulcanization. In the performance of the product, there has been a high-tear conductive silicone rubber and the addition of a certain metal to the silicone rubber Powder is a kind of pressure-conducting silicone rubber that conducts pressure parts and insulates where it is not pressured.
       Since conductive silicone rubber has the advantages of small size, stable and reliable contact, good shock resistance, convenient replacement, etc., 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 volume 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) On the premise of improving conductivity, maintain and improve the molding processability, mechanical properties and other properties of conductive silicone rubber;
(2) Improve conductivity while reducing filler filling;
(3) Develop new varieties of conductive materials and broaden application areas.
        Technically speaking, the replacement of metal materials by polymer materials is a 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, and its application fields are gradually expanding, which inevitably puts forward higher requirements on conductive polymers.
