General facts

Polytetrafluoroethylene

Shortening: PTFE

Color: White

Common uses: Electrical applications in aircraft, robots, electrical machines, gaskets, pipes, filters, self-lubricating bearings, coating in pans, foil, surface coating in chemical equipment, electrical insulation material, etc.

Benefits

  • High chemical resistance.
  • 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.
  • Not degraded by UV radiation. • Not attacked by microorganisms.
  • Good electrical and dielectric properties.
  • Very low water absorption.

Restrictions

  • 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.
  • Limited load capacity.

Specific properties

Fluorosint® HPV is similar to variant 207, approved by the FDA for food contact. However, European standards are not met. This variant is designed to withstand high PV values and also shows improved load-bearing capacity. The material is used, for example, in bearing bushings.
