Ceramic Band Heaters

Backer Marathon Ceramic Band Heaters are a high performance alternative to traditional mica band heaters.  Ceramic band heaters are capable of operating at temperatures up to 1400°F with the ceramic fiber insulation providing excellent thermal efficiency.  Ceramic band heaters are typically used for injection molding, extrusion, and blow molding. Ceramic band heaters can open fully for easy installation around the barrel.  Backer Marathon ceramic band heaters are available in 2 thicknesses; Standard and Double Insulated for maximum insulation thickness.
