Abstract: A vulcanizing agent for rubber is incorporated into a polymer which is substantially noncrosslinkable by the agent but which is fusible with rubber upon milling. The resulting polymeric mixture and a vulcanizable rubber are formed into strips which are joined together along the lengths thereof to form an elongated, two-component tape wherein the rubber vulcanizing agent is carried in the nonreactive polymer. Sections of the tape can be milled to produce a vulcanizable compound by blending the polymeric component with the rubber component, thus obviating any need for separate addition of a rubber vulcanizing agent. The tape can be wound on a reel and stored until the need for blending arises. Premature reaction of the vulcanizing agent with the rubber is prevented since it is bound within the noncrosslinkable polymer.
