Mica Tube

Mica

Mica tubes are typically made by combining mica paper or split mica with a suitable binder, such as silicone or epoxy. This mixture is then molded into tubes through a process that enhances their structural integrity and insulating properties. The most common method involves con-volute winding, which helps in minimizing seams and maximizing durability. This design allows mica tubes to offer continuous insulation coverage, providing an effective barrier against heat, moisture, and electrical transmission.
