Co-extrusion conductive gasket



Product description
Co extruded conductive silicone rubber material is composed of conductive rubber and non-conductive silica gel. It has excellent shielding efficiency, good water / gas sealing performance and corrosion resistance. The material can maintain long-term stability over a wide temperature range. Conductive silica gel mainly contains Ag / g, Ag / Al and Ni / C materials, which can meet the use requirements of customers through a variety of cross-section shapes.
Coextrusion material can save more space and cost, and achieve good air tightness and shielding effect at the same time. Non conductive rubber can provide excellent mechanical properties and reliability, and the conductive part can provide excellent shielding effect. And it can also provide more excellent compressibility during installation.
