PVDF
PVDF is a semi-crystalline polymer obtained from the polymerization of vinylidene fluoride, which, thanks to its composition made up of more than 50% Fluorine, combines excellent anti-adhesion and abrasion properties with modifiable mechanics, ranging from very flexible to rigid, and exceptional chemical resistance. It is an extremely pure polymer that does not need stabilizers, plasticizers, lubricants or flame retardants. PVDF is a polymer that can be adapted to the demands of the user and is available on the market in both flexible and rigid grades, the latter of which has a high modulus and tensile strength. Furthermore, PVDF maintains its characteristics within a wide range of temperatures. It can be found in various forms: foams, granules, powders, as well as coatings, thin, flexible and transparent films or even filaments and hoses. It has optimal creep resistance and is able to maintain such resistance under low loads at up to 140 °C. It also exhibits optimal thermal stability even for extended exposure at 150°C. Among the fluoropolymers, PVDF is the mostly easily transformable by normal technologies, which is the reason why it is found in all fields of application, from painting to substitutions for structural components. It has excellent abrasion resistance and is intrinsically fireproof. Among PVDF’s numerous properties, its resistance to ultraviolet radiation stands out; even after several years of exposure, its characteristics remain unimpaired by UV rays. PVDF offers excellent resistance against oxidation from ozone exposure. The crown jewel of this material is its resistance to nuclear radiation, which, in combination with its chemical resistance, makes it an optimal component in nuclear cleanup systems.
