Features Of DuPont Hytrel DYM350BK TPEE

  1. High-performance thermoplastic elastomer (TPEE) with exceptional dynamic fatigue resistance.

  2. Excellent balance of toughness, flexibility, and creep resistance across a wide temperature range (–40 °C to 150 °C short-term).

  3. Outstanding resistance to oils, greases, and many common automotive and industrial fluids.

  4. Good processability via injection molding and extrusion, with low moisture sensitivity versus competing TPEs.

  5. Carbon-black pigmented grade (DYM350BK) offering inherent UV stability and consistent electrical conductivity for static-dissipative applications.

Typical Applications Of DuPont Hytrel DYM350BK TPEE

  1. Automotive under-hood components including air ducts, turbocharger hoses, and sensor boots.

  2. Industrial power transmission belts and timing belt covers requiring high resilience and heat endurance.

  3. Oil and gas downhole tool components exposed to hydrocarbons and elevated temperatures.

  4. Static-dissipative fluid handling systems in semiconductor manufacturing equipment.

  5. Heavy-duty cable jacketing and strain relief boots for robotics and automation systems.
