DESCRIPTION: Since 1961, Chomerics has invented and extended virtually every aspect of conductive elastomer materials technology from the earliest silver and silver/copper filled silicones to the latest and more cost-effective silver/aluminum and nickel/graphite composites. Today we offer the most comprehensive selection and highest quality products available anywhere. Each conductive elastomer consists of a silicone, fluorosilicone, EPDM or fluorocarbon-fluorosilicone binder with a filler of pure silver, silver-plated copper, silver-plated aIuminium, silver-plated nickel, silver-plated glass, nickelplated graphite, or unplated graphite particles.
The development of these composites is the result of decades of research and testing, both in the laboratory and in the field. Our proprietary filler powder technology allows us to carefully control the composition, size, and morphology of the conductive particles. Their precise, uniform dispersion within the resinous binders produces materials with stable and consistent electrical and physical properties. Chomerics’ conductive elastomers feature excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. All meet MILSTD- 810 requirements for fungus resistance. In addition to EMI shielding, these materials will provide an environmental or pressure seal if required. For those materials containing silver, both packaging and storage conditions should be similar to those for other silver-containing components, such as relays or switches. They should be stored in sheet plastic, such as polyester or polyethylene, and kept away from sulfur-containing materials, such as sulfur-cured neoprene, cardboard, etc. To remove dirt, clean the elastomer with water or alcohol containing mild soap (do not use aromatic or chlorinated solvents). These materials are produced in a virtually unlimited variety of molded, die-cut and extruded shapes and sizes.
