Detail Information
  1. FL2300 is a polyvinylidene fluoride modified copolymer with medium and high viscosity grades. It can effectively enhance the force between polymer molecules, active materials and metal pole pieces, and improve adhesion and corrosion resistance in electrolyte. The unique structure can effectively prevent the slurry gel and improve the flexibility of the electrode sheet. It is especially suitable for the application of the high nickel ternary material system in the electric vehicle industry. 

  2. FL2300 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.

Features:  Modified copolymer, medium to high viscosity

Uses :  NCM811NCA and other high nickel system lithium battery binders 

Forms: White powder

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.
