Mica heaters:

They are used in equipment and systems that use thermal energy transferred by conduction. The greatest possible area of ​​contact between the resistance and the surface through which heat is transferred and the firmness of this contact are of great importance to achieve good efficiency and ensure a longer life. For this reason heaters are generally installed pressed.

For its construction, resistive wires of rectangular cross-section, coiled and insulated in laminated mica are used, for some applications they are shielded in stainless steel. Mica is a good electrical insulator and excellent heat conductor.


  • Maximum operating temperature 500 ° C.
  • Heat transfer by conduction.
  • Temperature uniformity at the receiving surface.



  • Household irons.
  • Presses to Vulcanize.
  • Stamping machines.
