Polyvinylidene fluoride (PVDF) is valued for its toughness, stability, and distinct engineering advantages. For example, if you need a polymer that will withstand exposure to harsh thermal, chemical, or ultraviolet conditions, PVDF offers superior stability similar to the performance of fluoropolymers in these environments.
PVFD is the homopolymer of 1, 1-di-fluoro-ethene. Its highly desirable insolubility and electrical properties result from the polarity of alternating CH2 and CF2 groups on the polymer chain. An extremely hard material, PVFD may be used at temperatures from -80 to 300°F (-62 to 149°C). No oxidation or thermal degradation occurs during continuous exposure to 300°F (149°C). It is available for custom molded shapes.
Polyvinylidene fluoride (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 ultraviolet radiation. It retains its properties in high vacuum and gamma radiation and is resistant to most acids and alkalis. PVDF is the material of choice when the porous structure will be exposed to ozone or chlorine.
Average pore size in micrometers: 25.
