Introduction for PVDF

PVDF is the abbreviation of polyvinylidene fluoride, which is a highly non-reactive thermoplastic fluorinated polymer with a translucent or white powder or granules. It can be synthesized through the polymerization reaction of 1,1-difluoroethylene, soluble in strong polar solvents such as dimethylacetamide, and has excellent properties such as anti-aging, chemical resistance, weather resistance, and ultraviolet radiation resistance.

PVDF is mainly used in engineering plastics, coatings, insulating materials, and ion exchange membrane materials. In the electronics industry, it can be used to make coatings, cable sheaths, printed circuit boards, heat shrink tubes, capacitor dielectrics, etc.; in the chemical industry, it can be used to make pumps, valves, pipe fittings, wire diaphragm plates, filter membranes, gaskets and other wear-resistant and corrosion-resistant parts; at the same time, it can also be used in the weapons industry, machinery industry, and indoor and outdoor decoration and protection.

In addition, PVDF also has important applications in the field of lithium-ion photovoltaics, and is an upstream material for semiconductor lithium-ion photovoltaics. Due to its excellent chemical resistance, processability, fatigue resistance and creep resistance, PVDF is also widely used in the storage and transportation of high-purity chemicals in the semiconductor industry. At the same time, in lithium batteries, PVDF is also used as a porous membrane, coagulant, adhesive separator, etc.
