Polyvinylidene fluoride – PVDF  shows a higher tensile strength, pressure resistance and dimensional stability than the related PTFE, but friction and insulation properties are lower. PVDF has a high mechanical strength and toughness at lower temperature and it’s self-extinguishing. The temperature ranges from -30 °C to +150 °C. PVDF shows a high resistance to chlorine, bromine and high-energy radiation.


Types:

  • PVDF
  • PVDF-ELS (electrically conductive)

 

Properties:

  • high tensile strength
  • high mechanical strength
  • high rigidity (also at low temperature)
  • high chemical resistance
  • very low water absorption
  • good friction and wear and tear values
  • self-extinguishing
  • high UV–resistance
  • toxic fumes when burned
  • relatively high coefficient of thermal expansion

 

Applications: Gaskets, pumps, rotation discs, valves, flap traps, centrifugals of extraction, fittings, glide tracks…
