Advanced Elastomer Systems Trefsin® 3201-75 W305 Thermoplastic Rubber

 

Subcategory: Elastomer, TPE; Thermoplastic

Close Analogs: This grade is no longer a commercial product

Material Notes:
A natural 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. Data provided by Advanced Elastomer Systems.
