BELPAMICA MICA SHEETS

  • Mica (vermiculite) is a natural product of aluminium silicate complexes; it is characterized by its layered morphology and an almost perfect basic division. The structure is highly flexible and of great elasticity and hardness. It has excellent thermal stability and chemical resistance.
  • The BelpaMica mica sheet is a material for high temperatures, which consists of compressed exfoliated mica on a sheet of perforated 316 stainless steel with no type of binding material.
  • Mica is used for high temperature and low pressure gaskets; it’s especially designed for uses where the temperature, together with the fluid and the environment, may cause corrosion in materials such as graphite.
  • It is recommended for high temperature turbines, turbochargers, high temperature heat exchangers, dry warm-air installations, and generally in high temperature applications.
  • In the automotive industry, mica is used for exhaust pipes and engines.
  • In the chemical, petrochemical, and refinery industries, mica is used for processes which operate at high temperatures (mainly pyrolysis and catalysis).
