Fluon®PFA is a copolymer of tetrafluoroethylene (C2F4) and perfluoroalkoxyethylene, which has excellent chemical, electrical, mechanical and surface properties.
PFA retains many inherent characteristics and similar properties to PTFE but can be processed using conventional thermoplastic techniques, such as extrusion, injection moulding, blow moulding, or electrostatic powder coating.
Fluon®PFA can be used within a wide temperature range from extremely low temperatures to 260℃ maximum without losing its properties.


Fluon®PFA is the most suitable material for semiconductor equipment parts, which are in constant contact with strong chemicals.

  • Outstanding chemical resistance
  • High mechanical strength
  • Good electrical properties
  • Noncombustibility
  • Low surface energy
  • Outstanding weatherability

Chemically stable material not affected by most chemicals

Retains high mechanical strength and can be used within a wide operating temperature range from -200℃ to +280℃.

Outstanding insulating material with a very low dielectric constant and a very low dielectric dissipation factor, for higher reliability in the electronics field.

Oxygen index at 95% or more; noncombustability resin for use in various fields.

Low friction, non stick, and high water and oil repellency surface characteristics; improved resin reliability gives improved properties, such as reducing resistance of fluids.

No deterioration caused by direct sun, wind, rain and exhaust gas; characteristics do not change when exposed to the elements long term.

Fine molding grade Fluon® P-62XPT

Due to its high melt-viscosity, PFA was supposed to be unsuitable for melt-processing very fine parts, for example, injection molding thin component parts.
Fluon®PFA P-62XPT has broken this concept and has been specially designed with high melt flow characteristics.
Generally, to improve melt processability of thermoplastics, molecular weight of the resin is reduced but, as a result physical properties, such as tensile strength or MIT (flex life), also decline dramatically. P-62XPT, developed Asahi Glass solved this problem using an original Asahi Glass technique.
Although having a high MFR ( 24-36g/min), making P-62XPT very suitable for fine melt-processing, the reduction in mechanical strength has been minimised, compared with other PFA grades.

Fluon®PFA P-62XPT is suitable for molding of the following extremely fine products.

Of course, P-62XPT can be processed using other conventional thermoplastic techniques as well as injection moulding.
For example it can be extruded into extremely thin tubes, filaments, or an insulation coating for electric cables.
