Data Sheets for Download:

Polyvinylidene fluoride, or PVDF, is a fluorinated thermoplastic resin which has outstanding resistance to most mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols, halogenated solvents, and oxidizing environments. It also has outstanding aging resistance, with its properties remaining constant after many years.

  • Superior chemical resistance
    PVDF has a high chemical resistance to strong acids, aliphatics, and aromatics, and to numerous mineral organic compounds.
  • Remarkable fire resistant properties
    In the Underwriters’ test, PVDF was given the highest classification (V-O), indicating that it was non-flammable and self-extinguishing.
  • UV and gamma radiation stability
  • Very high dielectric and piezoelectric constants
  • Absolutely non-toxic
    PVDF can be used in repeated contact with food products. Its surface, like glass, is unfavorable to the proliferation of microorganisms.
  • Good mechanical properties in tension as well as in deflection, torsion, and compression compared to other fluorinated polymers
  • Does not swell or alter in a wet environment
  • Uses standard machining and welding techniques

TECAFLON® PVDF’s excellent chemical and physical properties and the ease with which it can be processed make it especially suitable for components in the chemical, petrochemical, hydrometallurgical, pharmaceutical, food, nuclear, and paper and pulp industries, as well as the semiconductor processing industry.
