Liquid Silicone Rubber (LSR) is a two-component system, where long polysiloxane chains are reinforced with specially treated silica. Component A contains a platinum catalyst and Component B contains methylhydrogensiloxane as a cross-linker and an alcohol inhibitor. The primary differentiator between liquid silicone rubber (LSR) and high consistency rubber (HCR) is the “flowable” or “liquid” nature of LSR materials. While HCR can use either a peroxide or a platinum curing process, LSR uses only additive curing with platinum. Due to the thermosetting nature of the material, liquid silicone rubber injection molding requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and vulcanized.
