Enhanced Tear Resistant (ETR) High Consistency Rubber silicone elastomers for peroxide cure APPLICATIONS SILASTIC BioMedical Grade ETR Elastomers (Q7-4535, Q7-4550, Q7-4565) are uncatalyzed elastomer materials designed for compounding into elastomer for part fabrication and medical devices. DESCRIPTION SILASTIC BioMedical Grade ETR Elastomers (Q7-4535, Q7-4550, Q7-4565) are a series of one-part uncatalyzed silicone elastomer raw materials. The addition of a peroxide catalyst is necessary to accomplish vulcanization. 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 peroxide 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.
