Product Name.
White mica tube
Product Description.
Mica tube is a hard tubular insulating material made of high-quality mica, muscovite paper or phlogopite paper with appropriate adhesive by bonding and rolling. It is suitable for insulation of electrode rod or outlet bushing in various electrical appliances, motors, electric smelting furnaces etc.
Product Features.
1,Excellent high temperature resistance and insulation properties;
2,Good mechanical strength, stable chemical properties, excellent anti-erode and aging resistance. 3,Environmental friendly, non-poison.
4,Precise dimensions: adopting mechanical production and electronic measuring devices to monitor data
5, Beautiful shape, smooth inner and outer walls, good roundness and proportionality.
