MIL-DTL-83528C Type B

Silver-Aluminum Silicone Shielding Elastomer

SSP2368-65 is a 65-durometer (Shore A), electrically-conductive shielding silicone that’s filled with silver-plated aluminum particles and designed to meet MIL-DTL-8352C Type B requirements for elastomeric gaskets. For this particle-filled silicone, typical shielding effectiveness measurements for the 20 MHz to 10 GHz frequency band (E-field) are > 114 dB.

MIL-DTL-83528C Type B

SSP2368-65 meets the requirements of the MIL-DTL-83528C Type B specification for a silver-plated aluminum-filled silicone that’s capable of 100 dB of plane wave shielding effectiveness at 10 GHz. This conductive shielding elastomer from Specialty Silicone Products has a thermal stability range of -60°C to +220°C.
