Features Of API DT 20/CL1 TPE

  1. Thermoplastic elastomer (TPE) formulation with excellent processability via injection molding and extrusion.

  2. Halogen-free and RoHS-compliant, meeting stringent environmental and regulatory requirements for global markets.

  3. Good thermal stability up to 150 °C short-term, enabling reliable performance in moderate-temperature applications.

  4. Outstanding flexibility and resilience with Shore A hardness of 20, providing soft-touch feel and compression recovery.

  5. Compatible with polypropylene (PP) and polyethylene (PE) substrates for co-injection and overmolding processes.

Typical Applications Of API DT 20/CL1 TPE

  1. Soft-grip overmolding for hand tools, power tool housings, and ergonomic consumer appliances.

  2. Sealing components including gaskets, caps, and vibration-damping bushings in automotive interiors.

  3. Medical device grips and non-sterile housing components requiring biocompatibility support (ISO 10993-5 tested).

  4. Packaging closures and squeezable containers demanding tactile feedback and recyclability.

  5. Industrial hose covers and protective cable jacketing where flexibility and abrasion resistance are critical.
