Kemtron launches a flame retardant conductive elastomer for RFI/EMI shielding

Kemtron, the British manufacturer of RFI/EMI shielding gaskets, materials and components has launched a flame retardant, low smoke, low toxicity EMC shielding gasket. Tested and approved to the international standard UL94V-0 by Underwriters Laboratories for flame retardancy, file number E344902.

The material is a nickel coated graphite loaded into silicone elastomers, product code SNG-FR, the gasket provided a highly electrically conductive path between mating flanges of an electronics equipment enclosure giving a high level of RFI/EMI shielding.

Nickel coated graphite in silicone is the most cost effective of all the electrically conductive silicone elastomers and its performance in many applications will exceed that of silver based products due to its more aggressive surface finish providing a very low surface contact resistance. The material can be supplied as an extruded strip in various profiles, “O” rings or flat die cut gaskets. Electrically conductive pressure sensitive adhesive can be applied to flat gaskets to aid assembly.
