Duratec
Duratec materials are “technical ceramics” made from calcium silicate. They are formulated without the use of asbestos fibres, and are thermally and electrically insulating materials for high temperature use.
Thermal Properties
Non combustible and free of organic constituents; service temperature 1000°C; thermal conductivity decreases with increasing temperature.
Electrical Properties
High arc resistance; high surface and volume resitivity; high tracking resistance.
Mechanical/Chemical Properties
High strength over the full temperature range; machinable to close tolerances; high chemical stability in alkaline media; reactive in acid media; can be impregnated to become hydrophobic.
Applications.
- Element supports for the furnace industry
- Structural insulation within metal forming applications
- Electrical insulation generally
- Arc shields in switchgear
- High strength thermal and electrical separators
