Take you to learn more about mica products

mica products mainly include mica tape, mica board, mica foil, etc., all of which are composed of mica or mica powder, adhesives and reinforcing materials. Different material combinations can be made into mica insulating materials with various different characteristics. Mica tape is composed of adhesive, powder mica or flake mica, and reinforcing materials. It is mainly used for main insulation or phase insulation of high-voltage motors. Soft mica boards are divided into two types: soft mica boards and mica foils. The soft mica board is mainly used for motor slot insulation and end layer insulation.

Mica foil has B-grade shellac glass mica foil (5833), its dielectric strength is 16～35kV/mm; B-grade epoxy glass powder mica foil (5836-1), its dielectric strength is 16～35kV/mm; Grade H organosilicon glass mica foil (5850) has a dielectric strength of 16～35kV/mm; Grade F polyphenol ether polyimide film glass powder mica foil has a dielectric strength of 40kV/mm.

Mica is a rock-forming mineral, usually in the form of a pseudo-hexagonal or rhombic plate, sheet, or columnar crystal. The color varies with the change of chemical composition, and it becomes darker with the increase of Fe content. Mostly used in industry is muscovite, followed by phlogopite. It is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding rod, plastic, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigment and other chemical industries.

mica products are composed of mica or powder mica, adhesives and reinforcing materials. Adhesives mainly include asphalt paint, shellac paint, alkyd paint, epoxy paint, organic silicon paint and ammonium phosphate aqueous solution. Reinforcing materials mainly include mica tape, silk and alkali-free glass cloth.

mica tape is a ribbon-shaped insulating material made by bonding mica flakes or powdered mica paper and reinforcing materials with an adhesive, after drying and slitting. Mica tape has flexibility and windability at room temperature, good mechanical and electrical properties in cold and hot conditions, good corona resistance, and can continuously wrap motor wires.
