Description
Insulation Mica Tube M& P is a silicon bonded Muscovite or Phlogopite mica tube, a hard pipeinsulating material prepared by using Muscovite or Phlogopite mica paper With silicon bond agent and then processed by rolling.
Mica tubes are tubular insulating materials made from high - quality mica paper combined with appropriate adhesives, and processed through rolling, baking, and solidification.
They have excellent electrical insulation, high - temperature resistance, and mechanical strength, and are widely used in electrical equipment, the electronics industry, metallurgy, chemical engineering, and other fields.
Product Advantages of Mica Tubes from Hangzhou Weshare.
High - Quality Raw Materials
Selected Mica Raw Materials
Hangzhou Weshare only chooses high - quality mica ores as the raw materials for mica paper. These mica ores are characterized by high purity and large flake diameters, ensuring that the produced mica paper has outstanding electrical insulation and high - temperature resistance.
Environment - friendly Adhesives
In terms of adhesive selection, Hangzhou Weshare uses environment - friendly adhesives to ensure that no harmful substances are released during the production and use of mica tubes. These adhesives are not only environmentally friendly but also enable mica tubes to maintain good bonding performance during long - term use, preventing the delamination of mica sheets and extending the service life of mica tubes.
Standard supply
Customized dimension according to customer's drawing or requirements.
Storage
Two years quality guarantee from production date, under proper storage withtemperature ≤40°C and humidity >60% with Weshare original package.
