Material Notes:
A colorable thermoplastic elastomer which complies with FDA regulations for rubber articles intended for repeated use, as well as rubber articles in contact with non-fatty, non-oily foods as closures and sealing gaskets. It can be processed using injection molding, extrusion, blow molding or other melt processing techniques.Key Features: Excellent flex fatigue resistance; Excellent ozone resistance; May be used in contact with non-fatty foods as closure sealing gaskets in accordance with provisions of 21 CFR 177.1210 under the Federal Food, Drug and Cosmetic Act; Complies with 21 CFR 177.2600 "Rubber Articles Intended for Repeated Use"Additional processing comments: This thermoplastic rubber is a shear-dependent material that can be processed on conventional thermoplastic equipment for injection molding, extrusion, or blow molding. For extrusion, a general purpose screw with a compression ratio of 2.5 to 3.0 is recommended. Material can be recycled. VYRAM rubber is incompatible with acetal and PVC.Values below are for injection molded plaques, side gated, 82.6 mm x 117.5 mm x 3.0 mm. Tensile properties measured across flow.
