DESCRIPTION SILASTIC BioMedical Grade Liquid Silicone Rubbers (7-6830, 7-6840, Q7-4840, Q7-4850, 7-4860, 7-4870 and 7-6860) are a series of two-part platinum-catalyzed silicone elastomers specifically designed for liquid injection molding or supported extrusion. Each elastomer is supplied as a two-part kit (Part A and Part B), equal portions (by weight) 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 SILASTIC BioMedical Grade Liquid Silicone Rubbers are available in a range of nominal hardness from 30 to 60, 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.
