Polyvinylidene Fluoride, or PVDF is a highly
non-reactive and pure thermoplastic fluoropolymer.
PVDF is a specialty plastic
material in the fluoropolymer family; it is used generally in
applications requiring the highest purity, strength, and resistance
to solvents, acids, bases and heat and low smoke generation during
a fire event. Compared to other fluoropolymers, it has an easier
melt process because of its relatively low melting point of around
It has a low density (1.78) and low
cost compared to the other fluoropolymers. It is available as
piping products, sheet, tubing, films, plate and an insulator for
premium wire. It can be injected, molded or welded and is commonly
used in the chemical, semiconductor, medical and defense
industries, as well as in lithium ion batteries. It is also
available as a crosslinked closed cell foam, used increasingly in
aviation and aerospace applications.
A fine powder grade, KYNAR 500®
PVDF or HYLAR® 5000 PVDF, is also used as the principal ingredient
of high-end paints for metals. These PVDF paints have extremely
good gloss and color retention, and they are in use on many
prominent buildings around the world, e.g. the Petronas Towers in
Malaysia and Taipei 101 in Taiwan, as well as on commercial and
residential metal roofing.
PVDF membranes are used for western
blots for immobilization of proteins, due to its non-specific
affinity for amino acids
