Features Of DuPont Hytrel E5544 TPEE

  1. Excellent balance of strength, flexibility, and resilience across a wide temperature range (–40 °C to 150 °C short-term).

  2. Outstanding resistance to hydrolysis, oils, greases, and many common automotive fluids.

  3. High melt flow index enabling efficient processing via injection molding and extrusion.

  4. Good UV stability and inherent low-temperature impact toughness.

  5. Recyclable thermoplastic elastomer with no vulcanization required.

Typical Applications Of DuPont Hytrel E5544 TPEE

  1. Automotive air ducts and HVAC components requiring dimensional stability under thermal cycling.

  2. Power tool housings and grips demanding high impact resistance and ergonomic soft-touch feel.

  3. Industrial fluid handling hoses and couplings exposed to hydraulic oils and glycol-based coolants.

  4. Consumer appliance parts such as dishwasher pump impellers and washing machine door seals.

  5. Medical device tubing and connectors where biocompatibility (ISO 10993-compliant grades available) and kink resistance are critical.
