Description
Material Notes:
A black thermoplastic elastomer with excellent permeation resistance to water, air and other gases. It can be processed using injection molding, extrusion, blow molding or other melt processing techniques.Key Features: Permeability – Air permeation rate @ 23°C (73°F), (ASTM D 1434) 57 cm3.mm/m2.day.atm (Based on testing of 65A TREFSIN Rubber); TREFSIN rubber is also relatively impermeable to a wide variety of other fluids and gases, and exhibits good resistance to various chemicals, heat and weathering.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. TREFSIN 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.

This grade was removed from the Advanced Elastomers Systems standard product line before the ExxonMobil acquisiton.
