Ceramic fibre boards

Ceramic fibre boards

Asbestos-free thermal insulation board based on ceramic and stone fibres and binder-bonded fillers, with a temperature resistance of 850, 1100 oC, 1250 oC. Used as an electrical insulator. Very easy to cut, punch, machine and shape wet (smaller thicknesses).

This board is commonly used in the energy, metallurgy, and ceramics industries.

Features:

  • resistance to thermal shock,
  • low thermal conductivity,
  • good chemical resistance,
  • easy to process mechanically.
