- TECHNICAL DATA SHEEt: Key characteristics and APPLICATIONS

Polyvinylidene Fluoride (PVDF)

General Information:

  • Product Name: Polyvinylidene Fluoride (PVDF)
  • Classification: Semi-crystalline thermoplastic
  • Chemical Structure: Linear polymer composed of alternating vinylidene and fluoride units

 

Typical Properties:

  • Density: 1.75 – 1.78 g/cm³
  • Tensile Strength: 35 – 50 MPa
  • Elongation at Break: 20 – 300%
  • Tensile Modulus: 1.5 – 2.5 GPa
  • Hardness: Shore D 75-85
  • Melting Temperature: 165 – 175°C (329 – 347°F)
  • Continuous Use Temperature: -40°C to 150°C (-40°F to 302°F)
  • Flammability: V-0 (UL 94)
  • Dielectric Constant (1kHz): 8 – 9

 

Features and Benefits:

  • Chemical Resistance: Exceptional resistance to a broad spectrum of chemicals and solvents.
  • UV Resistance: Excellent resistance to UV and other radiation.
  • High Purity: Low ion and metal content makes it suitable for critical applications.
  • Weather Resistance: Maintains properties and appearance under prolonged environmental exposure.
  • Electrical Properties: Good insulator with a stable dielectric constant.

 

Applications:

  • Chemical Processing: Piping, tanks, and valves due to its chemical resistance.
  • Electronics: Wire insulation, printed circuit boards, and membranes.
  • Medical: Catheters and other medical devices.
  • Oil & Gas: Linings and coatings for steel pipes, and tubing.
  • Building & Construction: Architectural coatings and membranes for roofing.
  • Automotive & Transportation: Fuel system components and exterior parts.

 

Processing Methods:

  • Injection Moulding: Used for the production of detailed components.
  • Extrusion: Suitable for pipes, films, and sheets.
  • Blow Moulding: For containers and hollow components.
  • Welding: PVDF can be effectively welded using various techniques.

 

Environmental Impact and Recycling:

  • PVDF can be recycled, but specialised processes are required due to its chemical stability.
  • Post-industrial waste can be reprocessed, but high levels of post-consumer recycling are less common.

 

Storage and Handling:

  • Store PVDF in a cool, dry environment. It is stable under typical storage conditions.
  • Ensure adequate ventilation when processing to prevent inhalation of fumes.





Safety Information:

  • PVDF is inert and safe to handle in its polymer form.
  • During processing, fumes can be generated and should not be inhaled. Ensure proper ventilation and use appropriate personal protective equipment.

Note: This technical data sheet provides a general overview and typical properties of PVDF. Real specifications might differ depending on the manufacturer and specific product grade. For accurate details on a particular product, always refer to the manufacturer’s data sheets.
