Medical Grade Silicone Rubber

Stockwell Elastomerics manufactures rubber gaskets and rubber components for medical device applications that are non-implant and in an area of the device where there is no exchange of blood or bodily fluids. Stockwell Elastomerics’ medical grade compounds are USP Class VI rated and are often sterilized using gamma, autoclave and ETO with minimal effect on the rubber compounds. Sample swatches for trial sterilizations and other validation testing are available.

Common medical device applications include enclosure gaskets, housing gaskets, vibration or dampening pads. More often, Stockwell Elastomerics manufactures custom rubber parts for medical device OEMs to their engineering drawings. These custom medical components specify the type and durometer of FDA silicone rubber needed. These parts can be made from FDA grade liquid silicone rubber that can be injection molded or cut from FDA high consistency rubber (HCR). Both of Stockwell Elastomerics’ FDA silicone rubber types (LSR and HCR) are platinum cured, also referred to as addition cured. Platinum cured silicones are preferred for medical device applications because they do not generate organic acids commonly produced with peroxide cured silicone rubber.
