PVDF(Polyvinylidene fluoride) is a highly non-reactive thermoplastic fluoropolymer.It can be synthesized by the polymerization of vinylidene fluoride.PVDF is mainly used in occasions that have extremely high requirements for purity and require resistance to solvents and acid-base corrosion.Compared with other fluoropolymers,such as polytetrafluoroethylene,PVDF has a lower density (1.76g/cm-1.79g/cm).PVDF can be used to produce insulating sheaths for pipes,plates,films,substrates and cables.At the same time,it can also be injection molded or welded and is widely used in the chemical,semiconductor,pharmaceutical and defense industries.this model generally used to produce valves,liners,sealing gasket through injection molding technique,and film for lithium battery by extrusion processing.
PVDF has corresponding applications in industry,electronic appliances,chemical equipment,wires and cables,pipes,etc.It is mainly used as seals,gaskets,lining materials.The most widely used applications are High-end functional films such as piezoelectric films,solar back sheet films, lithium battery separating films.
