Patent ID: 8198357

Claim:
A method for producing a molded silicone rubber product comprising: a) feeding into a base feed line a liquid silicone rubber base comprising: i) at least one vinyl siloxane polymer; and ii) at least one hydride crosslinker; b) feeding into a catalyst feed line a catalyst master batch comprising: i) at least one catalyst; and ii) optionally, at least one vinyl siloxane polymer; c) feeding into an inhibitor feed line an inhibitor master batch comprising: i) at least one liquid injection molding inhibitor; and ii) optionally, at least one vinyl siloxane polymer; d) optionally feeding into an optional additive feed line an optional at least one additive; e) directing said liquid silicone rubber base and said catalyst master batch and said inhibitor master batch, and optionally directing said optional at least one additive, into the barrel of an injection molding machine; f) operating said injection molding machine, thereby mixing said liquid silicone rubber base, said catalyst master batch, said inhibitor master batch, and said optional at least one additive; and g) curing said mixed liquid silicone rubber base, catalyst master batch, inhibitor master batch, and optional at least one additive by heating.
