Extruder Band Heater

Extruder band heaters are specifically designed for high operating temperature applications. The external temperature of a ceramic band is approximately 400°F while the operating temperature can reach approximately 1400°F. Ceramic bands are manufactured with a stainless steel cover and are fiber insulated preventing heat loss making them highly energy efficient and reducing operating costs. The interlocking ceramics make these heaters flexible, less prone to expansion problems and with a good thermal conductivity, the fitting around a barrel is less critical than a Mica band. Ceramic Barrel Heater Bands are easy to install and have a long functional life.
