Hytrel® TPC-ET 4056

Hytrel TPC-ET 4056 is a low-modulus thermoplastic polyester elastomer (TPC-ET) with a nominal hardness of 40D and high impact resistance down to -40°C. It offers excellent toughness, resilience 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 4056 contains a non-discoloring stabilizer and provides good resistance to oils, industrial chemicals and solvents. It is primarily recommended for extrusion and compounding and can be processed on conventional thermoplastic equipment.

Key Features:

Low modulus with excellent flexibility
High impact resistance down to -40°C
Outstanding creep and flex fatigue resistance
Good chemical resistance to oils and industrial fluids
Non-discoloring stabilizer for enhanced color stability
Light-stabilized grade suitable for light exposure
Plasticizer-free with long-term property retention

Processing Form:

Extrusion
Sheet Extrusion
Film Extrusion
Coating
Calendering
