  • High thermal and temperature resistance
  • Excellent machinability to close tolerances
  • Large format
  • Tough and durable
  • Dust free surface
  • Asbestos free

Technical calcium silicates for induction furnaces

DURATEC® are asbestos fibre free calcium silicate boards made in a density range from 1400 to 1800 kg/m3.

DURATEC® boards are thermal and electrical insulation materials resistant to fracture and stable at temperatures up to 1000 °C. These large-sized boards are ideally suited for replacing asbestos containing materials in all industrial applications.

DURATEC® -1000 is a machinable engineering material with good thermal stability and electrical insulation properties.

Working & processing
< #Back#
DURATEC® products can be accurately machined with special processing machinery and appropriate tools. Accurate processing and shaping is usually a precondition for their use as precision parts in machines and plants.

When cutting to size and machining to shape, the maximum allowable workplace concentration for inhalable dust generation must be observed. Dust extraction is recommended.
