PVDF£¨Poly(vinylidene fluoride)£©

PVDF polyvinylidene fluoride, the appearance of translucent or white powder or granules, densely arranged between molecular chains, and strong hydrogen bonds, oxygen index of 46%, non-combustible, crystallinity of 65% to 78%, density of 1.77 ~1.80g/cm3, melting point is 172 ¡ãC, heat distortion temperature is 112~145 ¡ãC, long-term use temperature is -40~150 ¡ãC.

Poly(vinylidene fluoride), the English abbreviation PVDF, mainly refers to a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer, which has the characteristics of fluororesin and general-purpose resin, in addition to good In addition to chemical resistance, high temperature resistance, oxidation resistance, weather resistance, and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and thermoelectric properties, and is the second largest producer of fluorine-containing plastics. The largest product, the global annual production capacity exceeds 53,000 tons.

In the chemical structure, the fluorine-carbon bond is combined, and the structure with short bond properties forms the most stable and strong bond with hydrogen ions. Therefore, fluorocarbon coatings have specific physical and chemical properties, not only have strong abrasion resistance and impact resistance, but also have high resistance to fading and UV in extremely harsh and harsh environments.
