Industrial Extruder Barrel Mica/Ceramic/ Nozzle Band Heater
Ceramic Band Heater:
Ceramic band heaters are made of helically wound nickel chrome resistance coil precisely stretched and strung through steatite ceramic cores forming a flexible heating mat. It is then placed in flexible stainless steel housing with ceramic fibre insulation. These heaters are very flexible and can be fitted easily. Durable, ceramic band heaters provide excellent energy efficiency with their built-in ceramic fiber jackets. Unlike mica band heaters, ceramic heaters transfer heat through conduction and radiation and do not require tightening around the cylinder. Flexible, these heaters come in a wide variety of terminal styles, and with different clamping mechanisms, holes and cutouts.

Mica Band Heater
Mica band heaters are made of nickel chrome resistance ribbon precisely wound on specially selected mica sheet. It is then insulated and covered by metal sheathing and rolled to the required shape.
1. Stainless Steel sheath resists rust and high temperatures, and provides firm mechanical support.
2. Mica insulation prevents heat loss, thereby lowering energy costs.
3. High temperature nickel-chromium element wire
4. Max. watt density : 3 W/cm² (Wattage tolerance: +5% -10%)
4. Mini diameter: 25mm
5. Mini height: 25mm
