Steatite is a magnesium silicate – made up to 90% from soapstone. Particular feature: The extremely good process ability. Steatite is burnt at temperatures of between 1300°C and 1400°C. This safeguards both the high density and pronounced mechanical strength.
The capability to manufacture a wide range of extruded sizes accommodating both resistor and igniter manufacturers. Some component parts include ceramic heaters, ceramic resistors and ceramic igniters.
Here is where our customers turn to OFA:
- Switch and plug parts
- Insulating jacks
- Controller parts and casings
- Halogen lamp bases
- Heating conductor carriers and resistor cores
