Mica

Mica is commonly used in thermal and electrical applications due to its excellent electrical, thermal and mechanical stability. Mica products are often combined with a range of backing or composite materials, to improve mechanical strength or handling suitability.

Main Characteristics

  • High dielectric strength

  • Low electric loss

  • High surface and volume resistance

  • Excellent thermal stability

  • High shear and tensile strength

  • Inert to the action of water, acids, alkalies, oils and solvents

  • Fireproof and non-inflammable

  • Unaffected by temperatures from 640˚C to 880˚C

  • Resistant to the oxidising action of electrical discharges

Available forms include sheet, tube, roll or tape.
