Flexible Mica Sheet

flexible mica sheet

Flexible Mica Sheets is one popular insulation material with multiple layers of phlogopite/muscovite mica paper with high-temperature silicone resin, it’s bendable and high-tensile strength to be punched to insulation gaskets or mats for appliances, and furnaces.

Mica is a type of mineral that is widely used in many industrial applications because of its unique combination of physical and chemical properties. It is a good electrical insulator and has a high thermal resistance, making it an ideal material for use in electrical and thermal insulation. Mica is also very flexible and can be easily cut and shaped into a variety of different forms. In addition, it is resistant to chemical attack and can withstand high temperatures, making it a durable and long-lasting material.

Highmica is a professional manufacturer and supplier of industrial mica insulation materials, flexible mica sheets can be processed into shapes of different specifications, if you need a quotation, please click the link below.

 

Flexible mica sheets Properties

  • Flexible and high-tensile strength, most popular thickness 0.5~1.0mm, will be punched to heating protect mat, washers and insulation sealing parts.
  • Excellent thermal resistance, muscovite mica resist 500~700℃, Phlogopite mica resists 750~850℃, Synthetic/Muscovite Calcined mica resist more than 1000℃, most popular phlogopite mica sheet are used in the furnace.
  • Excellent electric insulation, normally the breakdown voltage is more than 16KV/mm.
  • Different flexible can be customized for different use. 
  • Customized mica sheet inserts with glass-fiber cloth, and stainless steel woven are available for special demand.
  • Eco-friendly and non-asbestos.

 

Application:

  • Electrical insulation: Flexible mica sheets are used as electrical insulation in a wide range of electrical and electronic equipment, including motors, generators, transformers, and appliances.
  • Flexible mica sheets are bendable and can be punched according CAD design. The flexible mica sheet mats are extremely fit the equipment as the insulation mat. Like the microwave oven, toaster
  • Flexible mica sheets can be cut into strips, and rolled into the sealing components, perfect expansion performance make a sealed joint and that can keep good performance even at high temperature. Such as automobile exhaust pipe
  • Flexible phlogopite mica sheets resist high-temperature more than 800℃, that’s very popular and used in induction, arc, and high-frequency furnace, also the mica sheets can combine with other materials to get multi-function and usage as customers demand, such as ceramic
  • Thermal barriers: Mica is used in the construction of thermal barriers to prevent the transfer of heat from one surface to another.
  • Industrial seals: Mica is often used as a sealing material in a variety of industrial applications, including pumps, valves, and compressors.

Flexible mica sheets are made from thin layers of mica that are bonded together with a flexible adhesive. They are known for their high electrical and thermal insulation properties, as well as their flexibility and durability.

How to make mica sheet?

The process steps to make Flexible mica sheet and Rigid Mica sheet is similar, just use different silicon resin, and the heat-pressing temperature and time are different. the basic steps are as follows:

  • quality muscovite mica paper, phlogopite mica paper, or synthetic mica paper with high-temperature silicon resin.
  • Heating press the mica paper to mica sheets.
  • Cutting the mica sheets to size: 1000*600mm, 1000*1200mm, 1000*2400mm
  • Packing each 50kg mica sheet with PE film, and carton box, then fix each 1tons mica sheet with wooden pallets.
