KTM3-Thermal insulation boards

KTM-3 type of thermal insulation materials are produced from a range of refractory ceramic fibers blended with organic and inorganic binder systems. The boards exhibit good chemical stability, resisting attacks from most corrosive agents. KTM-3 boards are negatively affected by Hydrofluoric (HF) acid, phosphorus acid, concentrated alkali. They do not contain any asbestos, while using there is no unhealthy gas secretion.



  • Two application temperatures up to 1260°C and 1430°C
  • High temperature stability
  • Low warpage
  • Low thermal conductivity
  • Excellent thickness control
  • Easy to cut by knife, cutting or grinding machines
  • Easy to fix by high temperature glue
  • Good flexural and compressive strength
  • Resistant to thermal shocks
