ABSTRACT:
A metal rubber gasket includes a central metal lamina sandwiched by two outer elastomer layers. The elastomer is a blend of a butadiene-acrylonitrile rubber and a random terpolymer of ethylene, alkyl acrylate and the mono alkyl ester of a dioic acid. Preferably the butadiene-acrylonitrile rubber is functionally modified with polar groups such as a carboxyl, amine, or hydroxyl groups.
