Packaging and storage

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.
