PVDF(polyvinylidene fluoride)

Polyvinylidene fluoride, or PVDF, is a fluorinated thermoplastic which has outstanding resistance to most mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols, halogenated solvents, and oxidizing environments.  It also has outstanding aging resistance, with its properties remaining constant after many years of continuous use.
