Silastic® BioMedical Grade ETR Elastomer Bases are one-part, uncatalyzed elastomer materials designed for compounding into elastomer for part fabrication and medical devices. ETR Elastomer Bases are composed of dimethyl and methylvinyl siloxane copolymers and reinforcing silica. High Consistency Rubbers are millable thermoset silicone elastomers that can be extruded continuously to form a desired size and shape before curing. The resulting elastomers range in hardness from soft to firm, 35 to 65 Shore A Durometer.
