5751 - Conductive fluorosilicone elastomer

5751 - Conductive fluorosilicone elastomer is a 45-durometer, electrically-conductive, silver-aluminum shielding fluorosilicone that is designed to meet MIL-DTL-83528 Type D.

Silver-Aluminum Conductive Fluorosilicone Elastomer

5751 - Conductive fluorosilicone elastomer is a 45-durometer (Shore A), electrically-conductive fluorosilicone compound that is filled with silver-plated aluminum particles and comparable to Parker Chomerics 1287 and 1298 EMI shielding materials for conductive elastomer gaskets.

MIL-DTL-83528 Type D

5751 - Conductive fluorosilicone elastomer is desgined to meet the requirements of MIL-DTL-83528 Type D for a silver-plated, aluminum-filled fluorosilicone capable of 90 dB of plane wave shielding effectiveness at 10 GHz, with a continuous use temperature range of -55°C to +160°C, and resistant to solvents and jet fuels.

Conductive Elastomer Gasket Materials

5751 - Conductive fluorosilicone elastomer 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.
