PVDF Polyvinylidene Fluoride Films

Tecfilm PVDF TC 0130

Polyvinylidene fluoride or PVDF is a highly reactive thermoplastic fluoropolymer, a polymer of vinylidene fluoride.

PVDF is a special plastic from the fluoropolymer family.

It is a semi-crystalline, semi-opaque and white engineering thermoplastic which is melt processable and very expensive. It has good temperature and general chemical resistance (although both are not as good as PTFE) and good resistance to abrasion and radiation. It is slightly stiffer and stronger than most (melt-processable) fluoropolymers, but has high dielectric losses.

It has a highly dipolar molecule, so that when the correct morphology is achieved, valuable piezo- and pyroelectric properties are obtained.

In practice, both uniaxial and biaxial mechanical orientations are used, which give a different equilibrium of piezo-/pyroelectric properties after poling.

It is generally used in applications requiring the highest purity, strength and resistance to solvents, acids, bases and heat and low smoke formation in case of fire. Compared to other fluoropolymers, it has an easier melting process due to its relatively low melting point.
