- Zheflon®FL2604 PVDF- Squeeze GradeDetail Information
Zheflon® FL2604 is a medium viscosity grade polyvinylidene fluoride copolymer with high purity. Important properties include excellent chemical resistance to most aggressive substances and solvents, excellent mechanical strength and toughness, high abrasion resistance, high temperature capabilities, excellent aging resistance, low permeability to most gases and liquids and easily melt-processed by standard methods of squeeze. Also can be used for the production of lithium battery separators.

1% wt. loss / in air1.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.
