Ceramic mat – Norgpol

Ceramic mat

Ceramic fibres are produced by centrifugation from molten silicon oxides and aluminium. White twisted clay-silicate fibres with high temperature resistance, low thermal conductivity and good chemical resistance are then obtained.

Refractory mats – application

Ceramic mats consist of clay-silicate fibers mechanically combined without additional binding measures. They are characterized by excellent strength for sudden temperature fluctuations. Thermal resistance of ceramic mattes is, depending on the type: 1260, 1430, 1600°C. Refractory ceramic mats are used in various industries as thermal insulation in the construction of furnaces, dryers, fireplaces. They are also used for the insulation of boilers, pipelines and cables as a classic insulating material. Ceramic mats are an ideal material for the production of modules.

Properties of ceramic refractory mats

Refractory ceramic mats available from NORGPOL show properties that allow them to be used in the toughest conditions. These include:

  • resistance to continuous load up to 1260, 1430, 1600°C;
  • good isolating properties;
  • high mechanical stability;
  • low annealing losses;
  • high chemical and thermal stability;
  • low specific weight and flexibility;
  • resistance to water, oils, fats, liquid metals and most acids;
  • good electro-insulating properties;
  • good acoustic properties;
  • ease of processing;
  • wide range of formats, uniform density, dimensional stability.
