  • Description
  • Product review

Zheflon® FL2600 is a low-medium viscosity grade PVDF copolymer that imparts flexibility to the polymer while reducing the crystallinity of the polymer. It enhances the interaction between polymer molecules, active materials and metal pole pieces. Force, improve adhesion performance, especially suitable for the application of lithium iron phosphate and lithium cobalt oxide systems in the electric vehicle industry.

Zheflon® FL2600 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 to 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.
