Features Of SK EP9170B/N TPE

  1. Thermoplastic elastomer based on SEBS (Styrene-Ethylene/Butylene-Styrene) copolymer matrix for excellent elasticity and resilience.

  2. Halogen-free formulation meeting stringent environmental and safety standards including RoHS and REACH compliance.

  3. Outstanding processability via injection molding and extrusion with low melt viscosity and minimal thermal degradation.

  4. Superior soft-touch surface feel and high abrasion resistance for premium end-user applications.

  5. Good adhesion to polypropylene (PP) and polyethylene (PE), enabling reliable two-component overmolding.

Typical Applications Of SK EP9170B/N TPE

  1. Automotive interior trim components, including gear knobs, armrest covers, and dashboard soft-touch overlays.

  2. Consumer electronics housings and protective grips for power tools, toothbrushes, and handheld devices.

  3. Medical device grips and ergonomic handles requiring biocompatibility-supporting material history (ISO 10993 pre-screened).

  4. Household appliance control panels and tactile buttons demanding long-term UV stability and color retention.

  5. Packaging closures and squeezable containers requiring flexibility, seal integrity, and food-contact suitability (FDA-compliant grades available upon request).
