Polyvinyl Fluoride - PVF

Polyvinyl fluoride is a semi-crystalline, colorless, transparent-translucent fluoropolymer comprising of good chemical resistance, exceptional weathering resistance and low permeability to gases; it has an extremely high tolerance of flexing and is very slow burning.

It is UV transparent, down to about 250 nm for the thinner films. However, it is extremely expensive and unfitting for injection molding since its melt decomposition rate is very fast.

Polymer Type



Excellent resistance to weathering, staining and chemical attack (except ketones and esters).  Exhibits very slow burning and low permeability to vapour.


Insufficient thermal stability to allow normal injection moulding.  Usually only available as a film.


Weather resistant film for glazing panels, surface covering for PVC film.  Film covering in aircraft interiors to reduce flammability, glazing for solar panels.

Normally, it is available as a film which is employed for exterior glazing, release film and surface protection.
