Kemtron, the British manufacturer of rfi/emi shielding gaskets, materials and components has launched a flame retardant, low smoke, low toxicity emc shielding gasket.
It has been tested and approved to the international standard UL94V-0 by Underwriters Laboratories for flame retardancy, file number E344902. It has also been tested for smoke density to BS 6853:1999: Annex D.8.3and oxygen index to BS EN ISO 4589-2:1999 confirming the material meets to requirements for minor internal use on vehicles category 1a such as gaskets for electronic enclosures.
This makes it highly suitable for applications in underground transportation, trains and other safety critical applications.
The material is nickel coated graphite loaded into silicone elastomers, product code SNG-FR, the gasket provides a highly electrically conductive path between mating flanges of an electronics equipment enclosure giving a high level of rfi/emi shielding. The material can be supplied as an extruded strip in various profiles, "O" rings or flat die cut gaskets.
