Plastic Materials for the New Generation
Another testament to the company's advanced plastics capabilities is KF Polymer (polyvinylidene fluoride resin), which is used in a variety of industries due to its excellent chemical resistance and electrical characteristics.
KUREHA KF POLYMER is most popularly used throughout the world as a binder for lithium-ion batteries. KUREHA KF POLYMER is offered in both powder (W series) and solution (L series) form. L series solutions use NMP (N-Methyl 2-pyrrolidone).
KUREHA KF POLYMER has high chemical resistance and good mechanical properties. One of its most remarkable characteristics is lower irregular bonding of the molecular chain than any other PVDFs, which leads to a perfectly crystallized polymer. Thanks to these properties, long-term and stable performance is obtained with a lower degree of swelling by organic electrolytes in the case of lithium-ion batteries.
