SSP502-65 vs. CHO-SEAL 6503

Nickel-Graphite Silicone EMI Gasket Material

SSP502-65 is a 65-durometer nickel-graphite silicone that is very electrically conductive and combines reliable environmental sealing with superior shielding against electromagnetic interference (EMI). A third-party shielding report and salt spray test are available for this EMI shielding elastomer.

CHO-SEAL 6503 EMI Gasket Alternative

SSP502-65 can be used instead of CHO-SEAL 6305. SSP also makes other CHO-SEAL EMI gasket alternatives. CHO-SEAL® is a registered trademark of Parker Chomerics. SSP is a HEICO company that makes its own EMI elastomers. We are not a Parker Chomerics distributor. 

Cost-Effective EMI Shielding

SSP502-65 offers performance levels that are comparable to shielding silicones with silver-coated particles. SSP502-65 is more cost-effective, however, and this EMI material isn’t subject to fluctuating silver prices. 

EMI Sheets and Rolls

SSP502-65 is supplied as fully-cured, conductive sheet stock or continuous rolls (SSP502-65-CR). See our EMI Sheet Sizes and EMI Roll Sizes for more information. SSP502-65 supports thinner, smaller, and lighter-weight designs.

Additional Technical Information

SSP’s EMI RFI silicones have lower minimum order quantities (MOQs) and shorter lead times than the competition.  For additional information about SSP502-65, see the Technical Data Sheet Safety Data Sheet (SDS), Salt Spray Test data, and a third-party EMI Shielding Report.
