What is Mica Tube?
Mica tube is a rigid or flexible insulating material manufactured from high-quality mica paper, bonded with high-temperature resistant silicone or epoxy resin, and then formed into tubular shapes through molding or rolling.
These tubes are widely used in electrical insulation and thermal protection thanks to mica’s natural properties:
High thermal resistance
Excellent dielectric strength
Non-toxic, asbestos-free, and eco-friendly
Compared with traditional ceramic or fiberglass tubes, mica tubes combine better machinability with superior heat endurance, making them an ideal choice for high-demand industrial environments.
