BALLSTON SPA, N.Y.—Specialty Silicone Products is offering a 60-durometer, nickel-graphite shielding silicone that the company claims meets the flammability requirements of UL 94 V-0, a flame-testing standard from Underwriters Laboratories.
The flame-retardant SSP-502-60-V0 is offered as a ready-to-mold compound, fully-cured conductive sheet stock, or as continuous rolls, SSP said in a new release. This particle-filled silicone supports gasket fabrication through a variety of manufacturing methods and provides environmental sealing and electrical conductivity.
SSP-502-60-V0 is a 60-durometer silicone that meets the requirements of UL 94 V-0 and provides effective EMI shielding. In electrical devices and equipment, electromagnetic interference (EMI) can cause problems ranging from the temporary disruption of circuits to system failure. By filling a silicone elastomer with metal or metal-coated particles, a compound can combine EMI shielding with environmental sealing. Nickel-coated graphite particles are a good choice because they balance cost with performance.
