Da/Pro Rubber manufactures a variety of conductive components, including conductive gaskets using electrically conductive rubber for applications ranging from EMI shielding gaskets to keypads. There are standard conductive silicone grades available for molding gaskets using either compression or liquid injection molding (LIM). Additionally, Da/Pro Rubber can also custom compound conductive rubber for customer specific conductive elastomer gasket applications.
Rubber is made conductive by the incorporation of special grades of conductive carbon black or various conductive fillers such as metal spheres, metal (such as silver or copper) or coated spheres (such as copper or silver coated glass or metal spheres). The level of electrical conductivity is dependant on the conductivity of the filler. Silver-filled elastomer is one of the most conductive, with values similar to copper wire. It is one of the most expensive conductive elastomers aside from platinum or gold-filled conductive elastomer. The level of electrical conductivity varies from static bleed to highly conductive (i.e. similar to wire). Many types of elastomers can be made electrically conductive. For example: Da/Pro Rubber has neoprene, nitrile, EPDM and Silicone elastomers with varying amounts of electrical conductivity, for use in conductive gaskets, touchpads or other applications.
Da/Pro Rubber can mold gaskets, touch pads or any other custom conductive component (made to your specification) using a variety of conductive elastomers including thermoplastic conductive elastomers.
