Liquid Silicone Rubber (LSR) raw material for medical device and component fabrication in the Healthcare Industry APPLICATIONS Silastic® Q7-7840 Liquid Silicone Rubber, Silastic ® Q7-7850 Liquid Silicone Rubber, and Silastic ® Q7-7870 Liquid Silicone Rubber, Parts A and B, are heat-cured elastomers for use by customers fabricating medical devices, including those intended for implantation in humans for less than 30 days and non-implant applications. Silastic Q7-7840 Liquid Silicone Rubber, Silastic Q7-7850 Liquid Silicone Rubber, and Silastic Q7-7870 Liquid Silicone Rubber are two-part platinum-catalyzed silicone elastomers specifically designed for liquid injection molding or supported extrusion. The 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 elastomers are thermally cured via an addition-cure (platinum catalyzed) reaction. When blended and cured as indicated the resulting elastomers consist of crosslinked dimethyl and methyl-vinyl siloxane copolymers and reinforcing silica. The elastomer can be used without any post-cure. Furthermore, the cured elastomer is heat stable up to 204°C (400°F), can be autoclaved, and exhibits high gas permeability compared with most other thermoset elastomers and thermoplastics. |
