Suspension polymerization and emulsion polymerization of vinylidene fluoride product performance comparison

Poly vinylidene fluoride (PVDF) are an important source of fluorine-containing resin, its capacity and volume second only to PTFE. Compared to other fluorine-containing resin, PVDF is not only has good weathering resistance, dielectric, piezoelectric properties, and its processing method, which can melt (PVDF temperature window is the largest of fluorine-containing resins), and can be dissolved in polar solvents are in many. Because of these characteristics, PVDF is widely used in exterior wall coatings, solar energy, lithium batteries, chemical processing and other fields, the technical issues are also leading enterprises of domestic concerns. Dr Liang Congqiang at the technical level of vinylidene fluoride suspension polymerization and emulsion polymerization is introduced in detail.
