Hytrel® TPC-ET 3078

Hytrel TPC-ET 3078 is a very low-modulus thermoplastic polyester elastomer (TPC-ET) with a nominal hardness of 30D. It offers excellent flexibility, high elongation, exceptional toughness, and superior resistance to flex fatigue, creep and impact. This grade contains a non-discoloring stabilizer and can be processed using standard thermoplastic techniques including injection molding and extrusion. Hytrel TPC-ET 3078 maintains performance across a wide temperature range and is plasticizer-free with good chemical and hydrocarbon resistance.

Key Features:

Very low modulus with high flexibility
High tensile strength and extreme elongation (up to 900%)
Excellent toughness and flex fatigue resistance
Good resistance to hydrocarbons, oils and many industrial chemicals
Non-discoloring stabilizer for improved color stability
Plasticizer-free with wide temperature performance range

Processing Form:

Injection Molding
Film Extrusion
Extrusion
Sheet Extrusion
Thermoforming

Processing Notes:
Desiccant drying at 80°C for 2–3 hours is recommended to achieve a moisture content below 0.08%. Hytrel TPC-ET 3078 has an optimal melt temperature of 200°C and a mold temperature of 35°C. For extrusion, drying at 70–90°C for 2–3 hours with a processing moisture content below 0.06% is recommended. Hytrel is incompatible with acetal and PVC. Please also refer to the injection molding and extrusion guidelines.
