Core Applications

Four Industries That Specify Muscovite Mica Tube

From electrical equipment insulation protection to motor isolation and heater thermal barriers — white muscovite mica tube delivers dependable performance across every demanding application.

Electrical Equipment

Provides essential electrical insulation protection across electrical equipment — control cabinets, distribution panels, busbar sleeving, and conductor isolation. Reliable dielectric barrier for 20 kV/mm voltage applications.

Electric Motors

Used for electric motor electrical isolation and insulation — rotor and stator bar sleeving, winding insulation. Protects motor components from high operating temperatures and electrical interference.

Heaters & Heating Elements

Electrical and thermal insulation for heaters — heating rod sleeving, heating element separators, and thermocouple protection. Prevents heat transfer to adjacent components while ensuring electrical safety.

Other High-Temperature Applications

Custom applications requiring high-temperature electrical insulation — industrial ovens, furnace peripherals, automotive under-hood sensors, and specialized OEM equipment with demanding thermal environments.
