Mica tube is made of mica paper with the appropriate adhesive in the single-sided reinforcement material, the rolling made of rigid tubular insulation material. It has a high mechanical strength, suitable for a variety of motors, electrical equipment in the electrode, rod or outlet sleeve insulation. The maximum density of STMAT mica tube is up to 2.0g / cm³, length 10mm-2000mm, diameter 4~300mm. Under normal circumstances, we are in accordance with the positive tolerance for inner diameter and negative tolerance for outer diameter as principle during production. At the same time we can produce tubes according to customer requirements, some special tube can be controlled within 0.2mm.

◆ ST-MMT: MUSCOVITE MICA TUBE 白云母管
Muscovite mica tube is one of the most common mica tubes. In addition to the
general muscovite mica characteristics, it also has a uniform density, stronger
mechanical characteristics, and more suitable for long-term application, with temp
up to 500°C and intermittent to 700°C.
白云母管是较为最常用的云母管，除具备一般白云母产品特征外，光通的云母管还具有密
度均匀，机械特性稳定等特点，更适合长期应用，正常耐温达500℃，间接耐温至700℃。
◆ ST-PMT: PHLOGOPITE MICA TUBE 金云母管
Phlogopite mica tube can be long time used during the temperature up to 700 ° C,
and intermittent to 700°C 1000 ° C. The color of phlogopite mica tube is divided
into three items according to the mica ore, which include black, yellow and green
respectively.
