Translucent, Uncatalyzed Silicone Rubber Base APPLICATIONS Dow Corning® QP1 Silicone Elastomer Bases are an uncatalyzed material designed for compounding into elastomer used for part fabrication of medical devices and device components including those intended for implantation in humans for less than 30 days and non-implant applications. DESCRIPTION Dow Corning QP1 Silicone Elastomers are a one-part high consistency rubber base which is supplied absent any catalyst. Once compounded with peroxide it can be used to fabricate parts by extrusion, calendaring or molding. When compounded and cured as indicated, the resulting elastomer consists of cross-linked dimethyl and methyl-vinyl siloxane copolymers and reinforcing silica. |
