Benefits

The benefits of PTFE applications

  • 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.
  • Exceptional water resistance.

Restrictions

The restrictions of PTFE + GF 25

  • 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.

PTFE + GF 25 – Specific properties

PTFE compound with 25% glass fiber has an improved creep resistance over all temperature ranges. This plastic allows some compression required for sealing in both gaskets and valves with little effect on the electrical properties. The 25% glass fiber functions as an insulator, has exceptional resistance to water and gives excellent chemical stability.
