Benefits

The benefits of PTFE plastic

  • High chemical resistance.
  • Excellent sliding properties.
  • Not attacked by acids, bases, and most organic solvents.
  • Withstands up to + 260 ° C continuously.
  • Tough at low temperatures down to -160 ° C.
  • Lowest friction of all plastics.
  • Non-stick surface.
  • Not degraded by UV radiation.
  • Not attacked by microorganisms.
  • Good electrical and dielectric properties.
  • Very low water absorption.

Restrictions

The restrictions of PTFE plastic

  • High melt viscosity makes the material difficult to work with.
  • Poor creep resistance.
  • High density relative to other plastics.
  • Attacked by molten alkali metals, fluorine gas, oxygen difluoride, and chlorine trifluoride (except PTFE).
  • Low abrasion resistance.
  • Low mechanical strength.
  • Limited load capacity.

PTFE plastic – Specific properties

PTFE material, with the chemical name polytetrafluoroethylene, is a semi-crystalline fluoropolymer with many unique properties. This fluoropolymer has unusually high thermal stability and chemical resistance as well as a high melting point. To improve the mechanical properties, PTFE plastic can be reinforced with additives such as

  • glass fiber
  • carbon
  • bronze.

Due to its structure, polytetrafluoroethylene is formed into semi-finished products in a compression process and then processed in cutting/cutting machines.
