A medically acceptable rubber composition to make into rubber products for contact with medical, drug and food products, said composition when cured having high tear strength and being substantially inert, said composition including at least 40% by weight of rubber comprising a mixture of brominated isobutylene-isoprene copolymer and a material selected from the group consisting of natural rubber and synthetic cis-polyisoprene, said composition further comprising a well-mixed minor amount of a polyolefin, with said composition being cured under static conditions at vulcanization temperature, and an effective amount of peroxide curing agent having been added to said composition at a lower temperature prior to curing, to achieve substantially complete cross-linking of the rubber and the polyolefin.
