PVDF
PVDF is polyvinylidene fluoride. Its appearance is translucent or white powder or particles. The molecular chains are closely arranged and have strong hydrogen bonds. The oxygen index is 46%. It is non-flammable. The crystallinity is 65%~78%. The density is It is 1.77~1.80g/cm3, the melting point is 172℃, the heat distortion temperature is 112~145℃, and the long-term use temperature is -40~150℃. In addition to its excellent chemical resistance, high temperature resistance, oxidation resistance, weather resistance, and radiation resistance, PVDF also has special properties such as piezoelectricity, dielectricity, and thermoelectricity. It is one of the most produced fluorine-containing plastics.
In the field of photovoltaics, PVDF, as a fluoropolymer, has excellent weather resistance and chemical corrosion resistance, and is often used as a coating material for solar cell backsheets. PVDF has a low surface energy and is easy to bond with other materials. Therefore, it is often used as a coating to be compounded with other materials to improve its surface properties.
