Polyvinylidene fluoride (PVDF) is the homopolymer of 1, 1-di-fluoro-ethene. Valued for its toughness and stability, PVDF is a thermoplastic that distinct engineering advantages. For example, its highly desirable solubility and electrical properties result from the polarity of alternating CH2 and CF2 groups on the polmer chain. If you need a polymer that will withstand exposure to harsh thermal, chemical or ultraviolent conditions, PVDF offers superior stability similar to the performance of fluoropolymers in these environments.

Available for custom molded shapes, the average pore size is approximately 25 micrometers. PVDF, an extremely hard material, may be used at temperatures from -80°F to 300°F (–62°C to 149°C). No oxidation of thermal degradation occurs during continuous exposure to 300°F (149°C). PVDF is a fluorocarbon and is classified as “Self Extinguishing, Group 1” by Underwriters’ Laboratories, Inc. It is unaffected by long term exposure to sunlight and other sources of ultra-violet radiation. It retains its properties in high vacuum and gamma radiation and is resistant to most acids and bases. PVDF is the material of choice when the porous structure will be exposed to ozone or chlorine.
