Hytrel® TPC-ET 6356 ECO-B 252

Hytrel TPC-ET 6356 ECO-B 252 is a medium-modulus thermoplastic polyester elastomer (TPC-ET) with a nominal hardness of 63D. It delivers the same mechanical and processing characteristics as Hytrel 6356 but is partially produced using bio-feedstock derived from waste according to the ISCC Plus certified mass balance method, reducing lifecycle greenhouse gas emissions and fossil resource use. The material offers excellent toughness, resilience, impact strength and outstanding resistance to creep, flex fatigue and tearing. Hytrel TPC-ET 6356 ECO-B 252 contains a non-discoloring stabilizer and provides good resistance to oils, fuels, industrial chemicals and solvents.

Key Features:

• Medium modulus with good stiffness
• High toughness and impact resistance
• Outstanding creep and flex fatigue resistance
• High tear strength and abrasion resistance
• Good chemical resistance to oils, fuels and industrial fluids
• Non-discoloring stabilizer for improved color stability
• Partially bio-based via ISCC Plus mass balance (ECO-B)
• 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 ECO-B 252 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 target 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.
