MediSil's Medical Grade Reinforced Unvulcanized Silicone Sheeting is a flexible, translucent, 50 durometer, uncured silicone elastomer sheeting material designed for limited stress, custom forming and bonding applications. Once vulcanized, the material can be cut and bonded with silicone adhesives. This reinforced Unvulcanized Sheeting is provided in a pre-catalyzed, unvulcanized form containing 2,4 Dichlorobenzoyl Peroxide. A woven or double knit polyester fabric reinforces the sheeting for dimensional stability and tear resistance.

This material was designed to meet ISO 10993 requirements for long term implantation. A sample from each manufactured lot is subjected to an MEM Tissue Culture test.

This product is manufactured to conform to GMP guidelines defined in CFR 21, Part 820. Compendiums, supported by FDA Master Files, are available. Additional testing is available on request.

Unvulcanized silicone sheeting may be formed and cured in place or used for press bonding cured silicones or other substrates. Remove polyethylene protective sheets. Post cure to stabilize properties if required. Press or hot air cure between 110C and 165C. Post cure for 2 hours at 165C to stabilize properties and remove peroxide residues. Clean with isopropyl alcohol or other appropriate cleaner.

A material safety data sheet is supplied with the shipment. No special precautions are necessary.

Post cure residue (2,4 dichlorobenzoic acid) must be properly handled in accordance with local, state and federal regulations.
