Applications

  • E/E parts (connectors, bobbins, insulators)
  • Automotive under-the-hood (pump housings, valve bodies, sensor brackets)
  • Chemical fluid handling (corrosion-resistant pumps/valves, fittings)
  • Industrial devices and appliances

Material selection tips

  • PPS / PPS+GF: heat/FR/chem-resistant → high-temp E/E & automotive structural parts.
  • PEEK / PEEK+GF: higher strength & wear → precision structures and long-load parts.
  • PVDF / PTFE / PFA: high-purity / extreme chem-resistance → wet process & ultra-pure media.
  • PP / PP+GF: lightweight / economical → general chemical-resistant structures.
