Polyvinylidene Fluoride (PVDF)

Polyvinylidenefluoride Thermoplastic

Polyvinylidenefluoride is a high crystalline thermoplastic with good mechanical, thermal and electrical properties. As a fluoroplastic, Polyvinylidenefluoride has excellent chemical resistance without the disadvantages of low mechanical values and difficult workability of other fluoroplastics. Our polyvinylidene semi-finished products – from which we also manufacture all finished products – are manufactured in extrusion or press processes.

Chemical resistance

PVDF is resistant to acids and alkaline solutions, salts and salt solutions, aliphatic and aromatic hydrocarbons, alcohols and aromatics. PVDF is not resistant to ketones, amines, fuming sulphuric acid, nitric acid or to several hot alkalis (concentration related). Dimethyl formamide and dimethyl acetamide dissolve PVDF.

Machining

In addition to its good welding suitability, PVDF can also be machined on machine tools. With the respective surface treatment, PVDF can be bonded with a special solvent adhesive. Fluoropolymers decompose at temperatures above approx. 360°C and form highly aggressive and toxic hydrofluoric acid. As polymer dust can form when the material is being machined, smoking should not be permitted at the workplace.
