TOPDA Polyvinylidene fluoride (PVDF) resin mainly refers to the homopolymer of vinylidene fluoride or the copolymer of vinylidene fluoride and a small amount of other vinylidene fluoride monomers. It has the characteristics of both fluororesin and general resin. The resin itself has good chemical corrosion resistance, high temperature resistance, oxidation resistance, weather resistance, radiation resistance, as well as piezoelectric, dielectric, thermoelectric and other special properties, so it is widely used in high-end functional films such as piezoelectric film, solar back plate film, lithium battery diaphragm, etc.
