Abstract: A process for providing a last curing vulcanizable multi-part rubber compound comprising feeding simultaneously streams of a first rubber compound, a second rubber compound, and optionally one or more additional rubber compound into an injection chamber of an injection press where the streams of rubber are combined, injecting the combined streams of rubber from the injection chamber at a pressure of at least 10,000 psi into a motionless mixer provided downstream of the injection, and feeding the blended rubber stream into a mold provided downstream of the motionless mixer. The first, second and optional additional rubber compounds exhibit a ts2 value of at least 1.5 minutes when measured at 190 degree C. The first rubber compound, the second rubber compound and the optional additional rubber compound are kept separate from each other until the fast-curing vulcanizable multi-part rubber compound is used.
