Zheflon®FL2100 PVDF is an ultra high viscosity grade polyvinylidene fluoride copolymer molecules containing polar functional groups can be enhanced between the polymer molecules, the active substance and force between the pole pieces of metal, and to improve the adhesion properties in the electrolyte corrosion resistance.

Zheflon®FL2100 PVDF can effectively reduce the amount of formula, reducing battery DC resistance, to improve the energy density of the battery charge and discharge performance, effectively inhibiting cell resistance changes during the cycle, and thus meet the needs of the automotive industry.

  • Process safety instructions
  • This product should be processed under 260℃ to avoid producing toxic gases.
  • PVDF has good fire resistance and smoke inhibition property. While, it will release toxic hydrogen fluoride gas and fluorocarbon compounds when meets with fire.
  • Operators should pay attention to personal protection during the processing and operating.
  • Packaging and storage

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.
