Plastic Screws PFA

Material name

Material name : Perfluoroalkoxy alkanes (PFA)

Material Overview

PFA has excellent heat resistance, chemical resistance and weatherability. It can be melt-molded, such as injection or extrusion. The high-purity PFA has made big achievements in the manufacturing process of semiconductors due to the low elution of fluoride ions and particles.

Beneficial Properties

  • It exhibits heat resistance, inertness for almost all chemicals and excellent weatherability.
  • Retains mechanical strength at a wide temperature range from-200°C to 260°C.
  • It has been used in many semiconductor sites due to its highly purity by stabilizing treatment of end groups.
  • It has excellent flame retardancy (limiting O2 index 95 vol%, UL94V-0).

Applications

PFA made parts, such as fasteners, pipe fittings, tubes,…are ideal for chemical applications, e.g.: pharmaceutical industry or Semiconductor wet chemistry process.
