Professional Analysis for Mica & Ceramic Elements
Band Heater Application Limits
To ensure maximum life of your band heaters, please follow these industrial limits for high-temperature applications:
| Heater Type | Max Watt Density | Max Operating Temp |
|---|---|---|
| Mica Band | 35 – 40 W/in² | 350°C (660°F) |
| Ceramic Band | 45 – 55 W/in² | 700°C (1300°F) |
Pro Tip: Ensure the band is tight. Even a 0.5mm gap between the heater and the barrel causes “air pockets” that lead to localized overheating and mica carbonization.
