ABSTRACT:
The invention provides a processing aid and method for lubricating and improving the processability and releasability of rubber and plastic without adversely affecting and, in certain instances, improving the physical properties of the rubber or plastic such as adhesion, tack, modulus and tensile strength. The processing aid comprises a pre-formed homogeneous mixture of at least one silicone fluid lubricant and at least one peptizing agent. A preferred processing aid also includes a silicone fluid wetting agent, which affords decreased vulcanization times and increased production rates.
