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.
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) 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.
