5000 Series EMI Shielding Monoshield

Gasket Material

Monoshield is intended for applications where the gasket is limited to 0.02 in. thickness and gap irregularities do not exceed 0.003 in. The material consists of a fine monel or aluminum which is expanded (as per MIL-S-46044) and impregnated with a 50 durometer silicone rubber. The manufacturing process exposes approximately 225 points of contact per square inch to provide an efficient EMI shield with a pressure seal good up to 50 PSI between mating surfaces. These gaskets should not be re-used after having been compressed.
