Kynar® PVDF homopolymers and copolymers have gained success in the battery industry as binders for cathodes and anodes in lithium-ion technology, and as battery separators in lithium-ion polymer technology. Arkema is the world's leading producer of PVDF. Our particular brand of high purity, battery grade PVDF resins are Kynar® Polyvinylidene Fluoride (PVDF) and Kynar Flex®. Arkema has been involved with lithium technology from the beginning, working closely with battery scientists to help develop the technology. We've been using our more than thirty years of experience in coatings and films to help design thinner, smaller lithium-ion batteries.
