Mica powder is a non-metallic mineral that contains multiple components, mainly SiO2, with a content generally around 49% and Al2O3 content around 30%. Mica powder has good elasticity and toughness. It is an excellent additive with characteristics such as insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, and strong adhesion. It is widely used in industries such as electrical appliances, welding electrodes, rubber, plastics, paper making, paint, coatings, pigments, ceramics, cosmetics, new building materials, etc., with extremely wide applications. With the continuous development of science and technology, people have opened up new application fields. Mica paper: Mica paper is made from high-quality muscovite, which is thermally or hydraulically peeled and broken into pulp and paper, and then cut into continuous rolls or single sheets. Characteristics and Application of Mica Tube: Mica tube is a hard tubular insulating material made by laminating mica or mica paper with appropriate adhesive and bonding it onto a single sided reinforcing material, and then rolling and processing it. It has high mechanical strength and is suitable for insulation of electrodes, rods, or outlet sleeves in various motors and electrical equipment. The length of the mica tube is 300-500 millimeters, and the inner diameter size is medium 6- φ 300 millimeters. Characteristics and Application of Mica Pad: Mica pads are washers, gaskets, pads, or other irregular parts made of hard plate-like insulating materials. It has good mechanical strength and electrical performance under normal conditions. Suitable for insulation of various electrical appliances, welding machines, lightning arresters, electric heating components, etc
