Synopsis:Polyvinylidene fluoride (PVDF) resin refers to the copolymer of vinylidene fluoride (VDF) homopolymer or VDF and a small amount of other fluorovinyl monomers. The relative molecular weight is 400000 ~ 600000, and its repeating units are - ch2-cf2 -, CH2 - and CF2 - units arranged alternately, so that PVDF resin has the characteristics of fluororesin and general resin, and has excellent comprehensive properties
