High Grade Li-ion Battery Material PVDF Powder

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.   Item Unit Test way Stand Purity % / More than 99.9%  Density g/cm3 D792 1.77-1.80  Melting point ℃ D3418 165-172  molecular weight / / 65-75 (230℃,5kg) / Melt Flow Index g/10min D3835 1-2 Characteristic viscosity dl/g DMA,30℃ 1.0-2.0  Rotary viscometer Mpa.s 1g/10ml NMP,30℃ >2500  solubility / NMP/DMP,30℃,1hr  clear solution  Shao Hardness D D2240 76-80  shrinking percentage % D955 2.0-3.0  Water absorption % D570 0.01-0.03  Thermal decomposition (1% Wt loos in air) ℃ TGA 370-390
