Surface-treated aluminum foil "Ranafoil"
Aluminum foil that can be repurposed for various applications while utilizing the properties of aluminum due to chemical treatment of the surface.
Chemical treatment is applied to the surface of aluminum foil to achieve oil-free foil. 'Ranafoil' is an aluminum foil that has been surface-roughened with acid. (1) In applications such as paint coating and lamination with films, it improves wettability and enhances adhesion due to surface roughness. (2) It improves adhesion with active materials such as LIB and EDLC, resulting in reduced resistance. 【Features】 ■TYPE-A: Foil that has been chemically cleaned ■TYPE-E: Foil that has been chemically roughened ■TYPE-CB: Foil that has been coated on the surface *For more details, please refer to the catalog or feel free to contact us.
