Raw materials for medical device fabrication in the Healthcare Industry APPLICATIONS Silastic® BioMedical Grade ETR Elastomers (Q7-4720, Q7-4735, Q7-4750, Q7-4765, and Q7-4780) are heat-cured high consistency silicone rubbers designed for use by customers fabricating medical devices, including those intended for implantation in humans for less than 30 days. DESCRIPTION Silastic BioMedical Grade ETR Elastomers (Q7-4720, Q7-4735, Q7-4750, Q7-4765, and Q7-4780) are a series of two-part, enhanced-tear-resistant (ETR) silicone elastomers that consist of dimethyl and methylvinyl siloxane copolymers and reinforcing silica. The elastomers exhibit a range of hardness from soft (20 Shore A) to firm (80 Shore A). Each elastomer is supplied as a two-component kit (Part A and Part B), equal portions (by weight) of which must be thoroughly blended together prior to use. The elastomer is then thermally cured via addition-cure (platinum-cure) chemistry
