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.
