Features Of API 1685/PS TPE

  1. Thermoplastic elastomer blend combining polystyrene (PS) matrix with thermoplastic rubber phase for balanced rigidity and elasticity.

  2. Excellent melt processability via standard injection molding and extrusion equipment without requiring special tooling or drying.

  3. Good chemical resistance to dilute acids, alkalis, and aliphatic hydrocarbons under ambient conditions.

  4. Low odor and low extractables profile, compliant with ISO 10993-5 for non-implantable medical device components.

  5. Recyclable within thermoplastic streams—supports circular economy initiatives in industrial manufacturing.

Typical Applications Of API 1685/PS TPE

  1. Overmolded grips and soft-touch handles for power tools and consumer electronics.

  2. Sealing rings and gasket components in HVAC and fluid control systems.

  3. Housings and enclosures for portable diagnostic devices and wearable health monitors.

  4. Automotive interior trim parts including bezels, knobs, and console inserts.

  5. Reusable packaging components requiring impact resilience and dimensional stability.
