    • PROBLEM TO BE SOLVED: To provide a composition developing a high level of elastomer characteristics and exhibiting solvent resistance and other characteristics at high levels. SOLUTION: A vulcanizable rubber composition comprises a cured fluorocarbon elastomer dispersed in a thermoplastic matrix comprising a fully fluorinated polymer and a partially fluorinated polymer. The processing temperature is below the melting point of the fully fluorinated polymer. The composition is produced by mixing a curing agent with an uncured fluorocarbon elastomer, the fully fluorinated thermoplastic material and the partially fluorinated thermoplastic material, heating the resultant mixture at a temperature and for a time sufficient to achieve vulcanization of the elastomeric material and simultaneously mixing the mixture by applying mechanical energy to the mixture during the heating step. A shaped product such as a seal, a gasket, an O-ring or a hose is readily formed from the rubber composition according to a conventional thermoplastic resin process such as blow molding, injection molding and extrusion.
