Plastic Screws PCTFE

Material name

Material name : Polychlorotrifluoroethylene (PCTFE)

Material Overview

PCTFE is a unique fluoropolymer that is capable of maintaining its physical properties at exceptionally low operating temperatures. PCTFE has been widely applied to the semiconductor industries. It absorbs virtually no moisture, meaning it offers great dimensional stability, and maintains its electrical properties in a high humidity environment. In addition, it excels in gas barrier properties, especially water vapor barrier which shows the best performance among the plastics.

Beneficial Properties

  • Heat resistance
  • Chemical resistance, Low permeability
  • Weatherability
  • Optical property
  • Flame retardant


  • Widely used in semiconductors, chemicals and electronic components.
  • Wet process fasteners
  • Sealing materials (packing, gasket)
  • Pump parts (casing, impeller, valve body, plug)
