Detail Information

Zheflon® FL2100 is a high-viscosity grade of polyvinylidene fluoride copolymer containing polar functional groups in the molecule, which can enhance the interaction between polymer molecules, active materials and metal pole pieces, also improve the adhesion performance and corrosion resistance in the electrolyte, which is particularly suitable for the application of  Lithium iron phosphate and ternary system in the electric vehicle industry.

Zheflon® FL2100 can effectively reduce the amount of formula, reduce the DC resistance of the battery, improve the energy density and charge-discharge performance of the battery, effectively increase the capacity retention rate of the battery during the cycle, and thus meet the needs of the automotive industry.

1.PVDF should be processed under 260℃,to avoid producing toxic gases;

2.PVDF has good fire resistance and smoke inhibition property, however, when meets with fire, it will release toxic hydrogen fluoride gas and fluorocarbon compounds;

3.Operators should take good care of personal protection during the use procedure and processing.


PVDF is packed in PE plastic bag and then be put into a drum with the net weight 25KGS. It must be stored in clean, cool, dry place.
