Application Industries

  • Semiconductor wet process / UPW systems
  • Water treatment & environmental engineering
  • Chemical processing & corrosion control
  • Food & pharmaceutical processes

Material Selection Highlights

  • PVDF: high purity, chemical resistance, weatherability → wet-process piping/fixtures, pump/valve bodies, viewing windows.
  • PFA / PTFE: extreme chemical resistance → highly corrosive media, ultra-pure uses.
  • PEEK / PEEK+GF: high strength & heat → precision structures and wear parts.
  • PPS / PPS+GF: chemical resistance / flame retardant → electrical/electronic parts.
  • PP / PP+GF: lightweight & economical → general structures and chemical-resistant equipment.
