Main Features

Mica sheet is a high temp insulating material made of quality mica materials and high-performance organic silicon resin after the melting and laminating process, widely used in electrical appliances such as toasters, hair dryers and warm air blowers, etc and other electric heaters which require high temp electro insulation.

  • Refractory silicone rubber composite layer of ultra-high strength stubborn fabric makes it have high mechanical strength;
  • It can maintain solid structural integrity at high temperatures or flame, and has excellent electrical insulation;
  • Low smoke, low flame and low smoke toxicity during combustion;
  • It can be processed to ultra-thin thicknesses and has excellent flexibility.

mica sheet comes in the form of rigid laminated sheet after laminating, pressing and baking process consisting of quality muscovite, phlogopite or synthetic mica paper impregnated with high temperature resistant organic silicon resin as a binding agent.

Fire resistance classification UL94 (94 V-0); BS479 (class 1); IEC 60371-3-3 conformity


Rigid mica sheets are specially developed to provide outstanding thermal and electrical insulation for different heating elements.It has a wide range of following applications:

To implement resistor support, especially for heating elements in toasters, and hair dryers.

To manufacture closed heating elements such as heater bands, heating elements, clothes irons and presses, kettles, cooking appliances, and heating elements for extrusion machines;

To use as thermal insulation in circuit breakers such as dividers between components affected by high heat loads.

Standard Supply:

Thickness: 0.10-1.90mm+/-0.05mm

Size: 1000*600/1200/2400mm

We customized strips or parts according to the customer’s drawing or requirements.
