Application: Binder for lithium ion battery positive electrode active material, generally mixed with NMP solvent
Appearance: White powder

Usage:
761A is a kind of powder - like polyvinyl fluoride product, which has good solubility in some solvents.
Compared with other brands of 761A, PVDF is more suitable as a lithium battery electrode binder material, less than similar products, thereby increasing the capacity of the battery.
761A is a kind of polymer material with high dielectric constant, which has high viscosity and adhesion in a certain solvent.
The lithium battery membrane electrode material made of 761A has good chemical stability, temperature stability and good workability.
