Hytrel® TPC-ET 6356

Hytrel TPC-ET 6356 is a medium-modulus thermoplastic polyester elastomer (TPC-ET) with a nominal hardness of 63D. It offers excellent toughness, resilience, high impact strength and outstanding resistance to creep, flex fatigue and tearing. The material maintains flexibility at low temperatures and retains mechanical properties at elevated temperatures. Hytrel TPC-ET 6356 contains a non-discoloring stabilizer and provides good resistance to many industrial chemicals, oils and solvents. It can be processed using conventional thermoplastic techniques including injection molding and extrusion.

Key Features:

• Medium modulus with good stiffness
• High toughness and impact strength
• Outstanding resistance to creep and flex fatigue
• High tear strength and abrasion resistance
• Good chemical resistance to oils, fuels and industrial fluids
• Non-discoloring stabilizer for enhanced color stability
• Light-stabilized for improved durability under light exposure
• Plasticizer-free with long-term property retention

Processing Form:

• Injection Molding
• Film Extrusion
• Extrusion
• Sheet Extrusion
• Other Extrusion
• Casting
• Thermoforming

Processing Notes:
Drying is recommended at 100°C for 2–3 hours to reach a processing moisture content below 0.08%. Hytrel TPC-ET 6356 has an optimal melt temperature of 240°C and a mold temperature of 45°C. For extrusion, drying at 90–110°C for 2–3 hours with a moisture level below 0.06% is recommended, with an optimal melt temperature of 230°C. Hytrel is incompatible with acetal and PVC. Please refer to the injection molding and extrusion guidelines for additional details.
