PVDF (Polyvinylidene Fluoride)

Traditionally, PVDF has been used in the architectural coating industry, the wire and cable industry, the chemical industry and high-purity industries (mainly semiconductors). PVDF combines excellent chemical resistance, relative ease of processing, high strength, rigidity and abrasion resistance. This combination of properties makes it a popular material for valves, pumps and bearings. Its high dielectric constant and dissipation factor impair the utility of PVDF as primary wire and cable insulation. However, PVDF is used extensively for secondary wire and cable insulation due to its fire resistance and low smoke emission characteristics. PVDF copolymers are frequently used as communication cable sheathing and jacketing rather than PVDF homopolymer because the copolymer exhibit greater flexibility.
