Features Of Merquinsa 45-40/15 TPU Elastomer

  1. Excellent abrasion and wear resistance for demanding mechanical service conditions.

  2. Good low-temperature flexibility down to –30 °C without significant loss of elasticity.

  3. High tensile strength and elongation at break, enabling robust dynamic performance.

  4. Outstanding oil, grease, and hydrocarbon resistance compared to conventional thermoplastics.

  5. Easy processing via injection molding, extrusion, and blow molding with short cycle times.

Typical Applications Of Merquinsa 45-40/15 TPU Elastomer

  1. Automotive interior trim components including gear knobs, instrument panel overlays, and door armrests.

  2. Industrial hoses and tubing requiring flexibility, kink resistance, and chemical resilience.

  3. Consumer electronics protective casings and soft-touch overmolded grips.

  4. Medical device tubing and non-invasive wearable component housings (biocompatibility compliant per ISO 10993–5).

  5. Footwear midsoles and outsoles where energy return and durability are critical.
