New Conductive Elastomer EMI Gaskets are Moldable and Fire Resistant
OCTOBER 18, 2002, WOBURN, MASSACHUSETTS-- Chomerics, a division of the Parker Hannifin Corporation, has introduced CHO-SEAL® 6371 conductive elastomer for shielding applications requiring EMI gaskets that are rated UL 94V-0 for fire resistance. CHO-SEAL 6371 materials can be fabricated into virtually any shape using both compression and injection molding processes. No post-curing is needed. This versatility allows the production of fire-resistant EMI gaskets in forms such as o-rings, broad sheets, and die-cuts. Excellent tear trim characteristics make 6371 material ideal for custom molded shapes. CHO-SEAL 6371 gaskets can also be over-molded on plastic or metal shielded housings, such as those used in servers, base stations, and communications switching equipment.
CHO-SEAL 6371 material is a nickel-graphite-filled silicone elastomer that provides EMI shielding effectiveness of above 80 dB from 100 MHz up to 10 GHz. The material's inherent corrosion resistance and reliable performance in extreme temperatures make CHO-SEAL 6371 gaskets appropriate for outdoor applications.
EMI gaskets made from CHO-SEAL 6371 material provide an economical solution for many EMI gasket applications. Actual pricing depends on gasket geometry, and part volume levels.
