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.

云母管是由云母纸配以适当的胶粘剂粘合在单面补强材料上，经卷制加工而成的硬质管状绝缘材料。它具有很高的机械强度，适用于各种电机，电器中的电极，棒或出现套管的绝缘。光通的云母管最大密度可达2.0g /cm³，长10mm-2000mm，直径4mm-300mm。

在正常情况下，我们按照生产中的内径正负公差和外径负公差为原则。同时我们可以根据客户要求生产，部分特殊规格可以控制在0.2mm以内。

◆ 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.

金云母管可以在高达700°C的温度下长时间使用，间断到700°C 1000°C。金云母管的颜色根据云母矿分为三个项目，其中包括黑色，黄色和绿色。
