Ceramic Heating Strips and Insulator Rings
One to eight hole strips for flexible ceramic pad heaters
A ceramic heating strip is an electrothermal component sintered from high performance ceramic and normally combined with a resistance heating layer. The result carries heat where a metal element would oxidise away: strips operate stably between 1000 and 1800 degrees C with a maximum working temperature of 1650 degrees C, or 3000 degrees F, and are supplied in one to eight hole configurations for 30 V, 60 V and 80 V flexible ceramic pad heater assemblies.
Key Benefits
- Stable operation between 1000 and 1800 degrees C where metal elements fail
- Maximum working temperature of 1650 degrees C, equivalent to 3000 degrees F
- One to eight hole geometry so one part family covers several heater ratings
- Better corrosion resistance and longer service life than traditional metal heating elements
- Efficient thermal conductivity combined with thermal shock resistance
Problems It Solves
- Metal heating elements oxidising and failing early at high process temperature
- Heater pads that cannot follow a curved or irregular workpiece
- Short service life driving repeated heater replacement on production equipment

Comparison With Other Ceramics
Compared with a traditional metal heating element, the ceramic strip offers better corrosion resistance and a longer service life at the same duty. Compared with a steatite insulator, the heating strip is designed to carry the element rather than only to isolate it.
Use Guide
- Confirm the pad voltage, 30 V, 60 V or 80 V, before selecting the hole configuration
- Support the strip along its length so it is not loaded in bending when hot
- Allow expansion clearance at the ends of a strung strip assembly
