Thermal Ceramics

KRST Therma Ceramicl products are the optimal choice for safety and quality

in high-temperature work environments.

Vacuum Forming

This product is made by pre-treating ceramic or bio fibers, blending them with organic and inorganic binders, and forming them through vacuum molding. It is customizable in shape and density based on customer specifications, with operating temperature determined by the fibers and binders used.

Properties

  • Low thermal conductivity
  • Low heat storage capacity
  • Strong resistance to thermal shock and durability
  • Lightweight, easy to process, and allows precise shaping
  • High-temperature and chemical stability
  • Excellent insulation performance, lightweight, and flexibility provide cost-effectiveness

Applications

  • Steelmaking start tubes, nozzle gaskets, and plugs
  • Tundish liners, tundish nozzles
  • Insulation for various furnaces and kilns, burner blocks (tiles)
  • Stopper cones for non-ferrous metal melting furnaces
  • Consumable thermocouple protection sleeves, piping protection, and flue liners
  • Combustion chambers for oil and gas boilers
  • Transport ladles for molten aluminum
  • Thermal equipment doors, sight holes for various furnaces
