Patent ID: 8063137

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; iii) at least one filler b) feeding into a catalyst feed line a catalyst master batch comprising: iv) at least one catalyst; and v) optionally, at least one vinyl siloxane polymer; c) optionally feeding into an optional inhibitor feed line an optional inhibitor master batch comprising: vi) at least one liquid injection molding inhibitor; and vii) 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, optionally directing said optional 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 optional inhibitor master batch, and said optional at least one additive; and g) curing said mixed liquid silicone rubber base, catalyst master batch, optional inhibitor master batch, and optional at least one additive by heating, wherein said base feed line feeds into the barrel of the injection molding machine, and said catalyst feed line feeds into said base feed line.
