Mica board, also known as Siloon Soft mica board, is a soft plate-like insulating material made by pasting high temperature silicone adhesive paint and B-grade natural mica flakes and baking and pressing. The silicone soft mica board has neat edges, uniform thickness, uniform distribution of adhesive paint and mica sheets, no foreign matter impurities, delamination and mica sheet leakage, and is soft under normal conditions. Silicone soft mica board is suitable for slot insulation and inter-turn insulation of large steam turbine generators, high-voltage motors and DC motors, outer insulation and soft liner insulation of electrical coils, and can also be used as various electromechanical equipment, electrical appliances, instruments, etc. Electric heating equipment for windings. Especially suitable for high temperature insulation of various power frequency furnaces, intermediate frequency furnaces, electric arc furnaces, etc. Steel, metallurgy and other industries. Silicone soft mica board has high heat resistance, dielectric and moisture resistance. The heat resistance class is H, and it is suitable for slot insulation and turn-to-turn insulation of small and medium-sized motors with an operating temperature of 180 °C. Silicone soft mica board rooms are separated by polyester film or wax paper, wrapped in plastic film bags and packed in wooden boxes.
