KYNAR® PVDF

Polyvinylidene Fluoride

PVDF, often referred to by its trade name Kynar®, is a high purity engineering thermoplastic with excellent chemical resistance, abrasion resistance, flame resistance, and UV stability.

PVDF is widely used for chemical tank liners and semiconductor equipment components.

Homopolymer PVDF exhibits higher strength and stiffness and has a higher heat deflection temperature than copolymer PVDF.

Copolymer PVDF is less stiff but has superior impact resistance and stress crack resistance.

 

PVDF Standard Sizes

SHEET 24"x48" (0.25"-4.0" thick)
48"x96" (0.125"-2.0" thick)
ROD diameter 0.375"-6.0"
  • Length, width, thickness, and diameter tolerances vary by size and by manufacturer
  • Custom sizes and colors available upon request
  • Many of our plastic materials are available as films with thicknesses of 0.029" or less

PVDF Grades Available

  • FDA compliant

NOTE: Several grades of Kynar are available. For additional information on PVDF plastic materials, contact us at (800)925-4855 or (619)477-4855..

 

PVDF is a high molecular weight thermoplastic polymer with excellent chemical inertness. It is highly resistant to oxidizing agents and halogens and is almost completely resistant to aliphatic, aromatics, alcohols, acids and chlorinated solvents. It is resistant to most acids and bases.

PROPERTIES:
Mechanically strong. High dielectric strength. Thermally stable. Resistant to low temperatures. Stable to ultraviolet and extreme weather conditions. Self-extinguishing and non-toxic.

San Diego Plastics stocks PVDF shapes manufactured by ENSINGER ENGINEERING PLASTICS.
Ensinger's tradename for this product is TECAFLON®™

TECAFLON®™ PVDF Datasheet


TECAFLON®™ (PVDF) combines typical fluoropolymer properties with the mechanical properties of more rigid thermoplastics.
Other properties include non-toxicity, high purity, a high heat-deflection temperature, and UV and gamma radiation resistance.
TECAFLON®™ is used in semiconductor processing, chemical processing and heat exchangers.
