Rigid mica sheet comes in the form of rigid laminated sheet after laminating, pressing and baking process, consists of quality muscovite, phlogopite or synthetic mica paper impregnated with high temperature resistant organic silicon resin as binding agent.
Fire resistance classification UL94 (94 V-0); BS479 (class 1); IEC 60371-3-3 conformity.
Rigid mica sheet are specially developed to providing 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, hair dryers.
To manufacture closed heating elements such as heater bands, heating elements, clothes irons and presses, kettles, cooking appliances,heating elements for extrusion machines;
To be used as thermal insulation material in circuit breakers such as divider between components affected by a high heat loads.
