Plastic Screws PTFE

Material name

Material name : Polytetrafluoroethylene (PTFE)

Material Overview

PTFE material (it is also known as Teflon®) is a semi crystalline fluoropolymer with many unique characteristics. This fluoropolymer has unusually high thermal stability and chemical resistance, as well as a high melting point (-200 to +260°C, short-term up to 300°C). In addition, PTFE products have excellent sliding properties, excellent electrical resistance and a non stick surface. PTFE plastics can be reinforced with additives such as glass fibre, carbon or bronze to improve its mechanical properties.

Beneficial Properties

  • Extremely high chemical resistance
  • Very good temperature resistance (-200+260°C, short-term up to 300°C)
  • Very low coefficient of friction
  • Low dielectric constant
  • Flame resistance

Applications

  • Chemical plant engineering (valves, pump components, fittings, hopper)
  • High purity for sensitive pharmaceutical and food type applications.
  • Excellent electrical insulator.
