P210 is a high-viscosity grade polyvinylidene fluoride homopolymer, which contains polar functional groups in the molecule, which can enhance the force between polymer molecules, active materials and metal electrodes, improve adhesion performance and corrosion resistance in electrolyte, it is especially suitable for the application of lithium iron phosphate and ternary material system in the electric vehicle industry.
It can effectively reduce the amount of formula used, reduce the DC internal resistance of the battery, improve the energy density and charge and discharge performance of the battery, and effectively increase the capacity retention rate of the battery during the cycle, thereby meeting the needs of the automotive industry

Process safety instructions
1) This product should be processed below 260ºC to avoid the generation of toxic gas.
2) PVDF has good flame retardant and smoke suppression properties, however, when encountering a fire, it will release toxic hydrogen fluoride gas and fluorocarbons.
3) Operators should pay attention to personal protection during processing and use.
Packaging and storage
Packed in polyethylene plastic bags, then put them into cardboard drums, each with a net weight of 25Kg, and store them in a clean, cool and dry place.
