Features Of DuPont Hytrel 3078 TPEE

  1. Excellent balance of thermoplastic processability and elastomeric performance.

  2. High resistance to flex fatigue and dynamic stress under repeated bending.

  3. Good chemical resistance to oils, greases, and many automotive fluids.

  4. Retains mechanical properties across a wide temperature range (–40 °C to 150 °C short-term).

  5. Outstanding creep resistance compared to conventional TPEs and soft thermoplastics.

Typical Applications Of DuPont Hytrel 3078 TPEE

  1. Automotive air ducts and HVAC components requiring dimensional stability and vibration damping.

  2. Fuel system components including quick-connect couplings and fuel line retainers.

  3. Power tool housings and ergonomic overmolded grips demanding impact resilience and tactile feel.

  4. Industrial hose covers and bellows exposed to cyclic flexing and environmental stress.

  5. Consumer appliance parts such as dishwasher pump housings and washing machine door seals.
