ABSTRACT:
Described is a method for producing a molded silicone rubber product using a liquid silicone rubber (LSR) base comprising at least one vinyl siloxane polymer, at least one hydride crosslinker, and optionally at least one injection molding inhibitor. The single LSR base is fed into a feed line, and into the feed line are fed an inhibitor master batch comprising at least one liquid injection molding inhibitor and at least one vinyl siloxane polymer, and a catalyst master batch comprising at least one catalyst and at least one vinyl siloxane polymer. The invention is further directed to: said LSR base; said inhibitor master batch; said catalyst master batch; and a molded silicone rubber article produced by the methods and compositions described herein.
