High Consistency Elastomer - Platinum Cure

Applied Silicone Corporation Implant Grade High Consistency Addition Cure Molding Systems HCRA(M) are two part platinum catalyzed silicone elastomers designed for use in processes where high strength molded parts are desired. This material is specially formulated for a long potlife and a molding cure profile.  HCRA(M) contains 100% by weight of dimethyl silicone elastomer when cured. This product is supplied in two components consisting of equal amounts of Part A and Part B which are strained through a 400 mesh (25 micron) screen to ensure freedom from particulate contamination. 

The stringent biocompatibility requirements imposed upon these materials make this series of elastomers ideally suited for use in critical medical devices. Custom formulation for radiopacity, color, etc. is available upon request. Important characteristics include:

Long mixed life for molding applications
• Blendable to modify durometer
• No volatile cure by-products
• Optional post cure
• Non-tacky surface
• Non-blooming
• No peroxide residues
• Tested under FDA protocol as a substitute to replace discontinued Dow Corning Medical Grade Silicone for long term implantation.
