Application

FPD production equipment / Semiconductor devices / Printed circuit board etching devices /
Metallic surface treatment equipment and facilities / Chemical plants

Characteristics

  • PFA is a plastic with excellent heat resistance, electrical properties, chemical resistance, and abrasion resistance. Most chemicals cannot penetrate PFA.
  • It has excellent non-adhesive and lubrication properties.
  • It also has high flame retardance which clears the UL 94 V-0 standard.
  • The properties and precautions of plastic screws⇒Plastic Screws

Precautions for Use

Because a cumulative pitch difference is created when PFA screws are manufactured, use these screws with nuts. If a nut is not used, use a 20 mm or less fit with female thread.
