Electric paper

Electrolytic capacitor paper (also known as electrolytic paper) is one of the three key materials that constitute aluminum electrolytic capacitors. It acts as the adsorption carrier of the electrolyte and forms the cathode of the aluminum electrolytic capacitor together with the electrolyte. At the same time, it also plays the role of isolating the foil at the two poles, also known as the isolation paper. The paper has the characteristics of high purity, uniform thickness and tightness, and uniform fiber arrangement. In addition, it has sufficient and necessary mechanical and electrical strength, and can provide good immersion and retention for the electrolyte.
