Liquid Silicone Rubber for device and component fabrication in the healthcare industry APPLICATIONS DOW CORNING Class VI Elastomers (C6-530, C6-540, C6-550, C6-560, C6-570) Parts A & B are platinum-catalyzed materials designed for part fabrication and medical devices, including those intended for implantation in humans for up to 29 days. DESCRIPTION DOW CORNING Class VI Elastomers (C6-530, C6-540, C6-550, C6-560, C6-570) Parts A & B are a series of two-part platinum-catalyzed silicone elastomers. Each elastomer is supplied as a two-part kit (Part A and Part B), equal portions of which must be thoroughly blended together prior to use. The elastomer is thermally cured via an addition-cure (platinum-catalyzed) reaction. When blended and cured as indicated, the resulting elastomer consists of crosslinked dimethyl and methyl-vinyl siloxane copolymers and reinforcing silica. The elastomers are available in a range of nominal hardness from 30 to 70, Durometer-Shore A. The elastomers can be used without any post-cure although if necessary, this may be employed to stabilize final properties. Furthermore, the elastomers are heat stable up to 204°C (400°F), can be autoclaved, and exhibit high gas permeability compared with most thermoset elastomers and thermoplastics.
