Cogemicanite 505 M

Rigid mica heater plates

Cogemicanite 505 M is a Mica laminate designed for providing outstanding electrical insulation at high temperature. The main application is in heating elements for industrial and household appliances which require at least one of the following properties
  • excellent resistance to heat up to 800°C
  • excellent electrical insulation
  • excellent microwave permeability
  • excellent punchability
  • high edge strength
  • environmentally safe and non-toxic
  • UL-94V-0 certified
  • IEC 371-3-3 conformity
 
Composition   Cogemicanite 505 M consists of approximately 90 % Cogemica Muscovite impregnated with a
    unique high temperature resistance silicone resin.
     
Properties and Applications   A special low smoke and blisterfree grade used in heating elements for hair dryers, hair
    setters, irons, tumble dryers, band heaters, nozzle heaters... It fully resists the extreme high
     
    temperature cycles typically encountered for example, in automatic toasters.
