High Temperature Insulation



Duratec® is available in 3 different grades: 750; 1000 and XP. Duratec® is a calcium silicate technical ceramic and is totally asbestos free. The range is ideally suited for high temperature use in thermal and electrical insulation.

Key Features:

  • Duratec 750® - High strength; excellent electrical performance and arc resistance.
  • Duratec 1000® - Excellent machinability and thermal stability.
  • Excellent surface and volume resistivity.
  • Excellent tracking resistance.
  • Excellent strength over temperature range.
  • Machinable to very close tolerances.
  • Stable to alkali media, reactive to acid media.

Temperature: Up to +1000ºC.

Applications: Duratec® materials are commonly used for arc shields in switchgear, general electrical insulation, furnace element supports and high strength thermal and electrical separators.

Duratec-XP® is a calcium silicate technical cermic which is reinforced with a glass fibre.

Key Features:

  • Toughness giving near 'plastic' performance.
  • Excellent strength at elevated temperatures.
  • Non-brittle material giving flexible behaviour.
  • Electrically inert.
  • Good physical and mechanical properties.
  • Easily machinable.
  • Thermal and electrical insulation properties.

Temperature: Up to +600ºC

Applications: Duratec-XP® is often used for induction furnace components and electrically insulating arc chutes.
