Hytrel® TPC-ET 5526 BK203
Hytrel TPC-ET 5526 BK203 is a medium-modulus thermoplastic polyester elastomer (TPC-ET) with a nominal hardness of 55D. This black, UV-stabilized grade offers excellent toughness, high impact strength and strong resistance to creep, tearing and flex fatigue. The material maintains flexibility at low temperatures and retains mechanical performance at elevated temperatures. Hytrel TPC-ET 5526 BK203 provides good resistance to oils, fuels, industrial chemicals and solvents, and is specially recommended for injection molding applications requiring high flow properties.
Key Features:
- Medium modulus with balanced flexibility
- Black, UV-stabilized formulation
- High flow behavior for injection molding
- Excellent toughness and impact resistance
- Outstanding resistance to creep, tearing and flex fatigue
- Good resistance to oils, fuels and industrial chemicals
- Plasticizer-free with long-term property retention
Processing Form:
- Injection Molding
Processing Notes:
Drying is recommended at 100°C for 2–3 hours to achieve a processing moisture content ≤0.08%. Hytrel TPC-ET 5526 BK203 has an optimal melt temperature of 230°C (min. 220°C, max. 250°C) and an optimal mold temperature of 45°C (maximum 55°C). Hytrel is incompatible with acetal and PVC.

Automotive, Fluid Power, Electrical, Consumer Goods, Equipment Industry.
Hardness:
55D
Delivery Form:
Pellets
Key Features of Hytrel TPC
Flexibility & Resilience
Unlike traditional rubber, Hytrel TPC can flex in multiple directions, cycle after cycle, long after rubber would break.
Durability
Hytrel TPC is an essential ingredient in applications that must endure a wide range of temperatures and tough conditions during years of service.
Enhanced Chemical Resistance
Exhibits excellent resistance to hydrocarbons and other fluids, making it suitable for demanding environments.
Sustainable Options
The Hytrel TPC ECO-B series utilizes a biomass balance approach, incorporating up to 72% renewable content without compromising material properties.
