Vermiculite boards type SF-400, SF-600, SF-750

High-temperature insulation boards on the basis of delaminated vermiculite and inorganic binders. The material does not contain asbestos and organic substances. Vermiculite is a layer of aluminum-magnesium silicate that expands at fast heating, creating ultra light granulated product. Boards and fittings are formed by pressing with addition of binders.

Properties

  • resistance to thermal shocks, 
  • low thermal conductivity,
  • good electric resistance, 
  • easy mechanical treatment,
  • stiffness and stability,
  • non-flammable material of class A1.
