PVDF Tube


PVDF Tube

Polyvinylidene Fluoride (PVDF) is the homo-polymer of 1, 1-difluoroethylene. We are offering PVDF Tubes from Kynar®, which are tough engineered thermoplastics with impeccable performance levels. As an Exporter, Importer and Supplier of PVDF Tubes, we offer the range in varied thickness as well as custom extrusion. The PVDF Tubes and a full range of fittings are available in diameters ranging from 20-200 mm as per ISO 10931.

Details :

  • Structured by alternating units of methylene and difluoromethylene
  • Creates a highly crystalline polymer having high polarity and sharp melting point
  • Characteristic stability of fluoropolymers and retained properties of conventional thermoplastic materials
  • Resins are a series of PVDF based copolymers similar to KYNAR ® homopolymer resins in terms of purity and chemical resistance
  • Additional chemical compatibility of resins in high pH solutions, increased impact strength at ambient and low temperatures, and increased clarity
  • Flex and regular grades available for tubes


Sizes :

  • 16 mm OD
  • 14 mm OD
  • 12 mm OD
  • 10 mm OD
  • 8 mm OD
  • 6 mm OD

Note : Variety of thickness available, custon Extrusion on demand.
