General facts

Polytetrafluoreten

Shortening: PTFE+Mica

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

Fluorescent® 207 / FG exhibits excellent creep strength, high dimensional stability and does not let through hot steam. The material complies with FDA Directive 21 CFR 175,300, ie the raw materials are approved in contact with food. However, European standards are not met.
