| Popis: |
Poly(vinylidene fluoride), PVDF, [CH2CF2]n, is the addition polymer of vinylidene fluoride, VDF, CH2CF2. It has achieved a high level of usage during the past 40 years based upon the excellent resistance to chemicals, weathering elements, and oxidants, as well as for special properties such as piezoelectric characteristics and fire resistance. It is a tough, high temperature thermoplastic finding use, eg, in super heated steam environments. It may be fabricated by a variety of techniques, including solvent-based or water-based dispersion processes as well as typical melt extrusion and radiation cross-linking processes. It is available from a variety of manufacturers. Copolymerization technology has produced thermoplastic resins with excellent flexibility.
