High consistency rubber raw materials for healthcare industry fabrication

APPLICATIONS
Dow Corning® Class VI Elastomers (C6-235, C6-250, C6-265) are uncatalyzed silicone elastomer bases designed for compounding into elastomer for part fabrication and medical devices, including those intended for implantation in humans for up to 29 days.

DESCRIPTION
Dow Corning Class VI Elastomers (C6-235, C6-250, C6-265) are a series of one-part uncatalyzed silicone elastomer raw materials. The addition of a catalyst is necessary to accomplish cure. The resulting elastomers range in hardness from soft to firm (nominally 35 to 65, shore A durometer). These materials may be blended if desired to achieve intermediate hardnesses.
After appropriate compounding with a catalyst, cure and post-cure, the elastomers are heat stable up to 204°C (400°F), can be autoclaved, and exhibit high gas permeability compared with most thermoset elastomers and thermoplastics.
