Mica Plates for Thermal Electrical Insulation in Appliances and Power Systems

Short Description:

Muscovite or Phlogopite Mica Plates are premium insulating laminates consisting of approximately 90% natural mica paper and about 10% high-temperature silicone resin, hot-pressed into rigid or flexible sheets. These mica plates provide exceptional electrical insulation and dielectric strength, along with excellent thermal resistance ranging from 500℃ to 1000℃, while maintaining mechanical strength and dimensional stability under thermal cycling or mechanical stress. The material also features low thermal conductivity, outstanding flame resistance, and stable chemical properties. It can be precisely machined into custom components such as gaskets, washers, heater-element supports, slot wedges, insulating spacers, and other structural insulation parts. Available in a wide range of thicknesses (from 0.1 mm to over 50 mm) and fully customizable in size, these mica plates are widely used in electric motor and generator insulation, transformers, high-voltage switchgear, household and industrial heating appliances, furnaces and metallurgical equipment, high-temperature sealing and gasket systems, and various thermal barrier or fire-resistant applications.
