Crosslinked pvdf
Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C2H2F2)n. PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids … See more PVDF is sold under a variety of brand names including KF (Kureha), Hylar (Solvay), Kynar (Arkema) and Solef (Solvay). See more PVDF may be synthesized from the gaseous vinylidene fluoride (VDF) monomer by a free-radical (or controlled-radical) polymerization process. This may be followed by processes such as melt casting, or processing from a solution (e.g. solution casting, See more Copolymers The copolymer Poly(vinylidene fluoride-co-hexafluoropropylene) or PVDF-HFP is used as a co-polymer in the blades of artificial turf See more In 1969, strong piezoelectricity was observed in PVDF, with the piezoelectric coefficient of poled (placed under a strong electric field to induce a net dipole moment) thin films … See more PVDF is a thermoplastic that expresses versatility for applications similar to other thermoplastics, particularly fluoropolymers.
