Exceptional purity and chemical resistance with moderate strength

  • High Purity and low extractables
  • Chemically resistant to most common solvents including acids, salts, oils and steam
  • Mechanical strength and toughness to 150°C (300°F)
  • Resistance to ultraviolet, nuclear radiation, and standard sterilization methods
  • Resistance to weathering and fungi

PVDF fasteners & flanges, also known as Kynar, are made from a tough engineered fluoro-thermoplastic that offers a unique balance of excellent chemical resistance and good strength properties.

PVDF fasteners & flanges have the characteristic stability of fluoropolymers when exposed to harsh chemical and ultraviolet environments but are much stronger mechanically than PTFE or PFA polymers.  PVDF fasteners & flange also excel in high purity and low-permeability applications such as pharmaceutical and semi-conductor processing.

PVDF fasteners & flanges are available in most metric and standard sizes. See our online store (top right) for common sizes or contact us for your specific requirements.
