SSP-553-80 is an 80-durometer, electrically conductive, silver-plated-copper shielding silicone that is designed to meet MIL-DTL-83528 Type K.


High-Durometer, Silver-Copper Silicone Shielding Elastomer

SSP-553-80 is an 80-durometer (Shore A), electrically-conductive, silicone compound that’s filled with silver-plated copper particles and has a typical shielding effectiveness of 110 dB (typical industry value). This metal-filled silicone shielding elastomer from Specialty Silicone Products (SSP) is electrically conductive

MIL-DTL-83528 Type K

SSP-553-80 is designed to meet the requirements of the MIL-DTL-83528 Type K for a high-durometer silver-plated, copper-filled silicone capable of 110 dB of plane wave shielding effectiveness at 10 GHz with a continuous temperature range of -45°C to +125°C.

Conductive Elastomer Gasket Materials

SSP-553-80 is supplied as fully-cured, conductive sheet stock or as ready-to-mold compounds. Catalyzed raw materials are available for press-cure molding and have a shelf life of six months. Uncatalyzed materials have an indefinite shelf life, but may require freshening after 1 to 2 years.
