China Stainless Steel Mica Insulated Electric Plastic Extruder Ring BHeater

Factory Supplied Mica Air Insulated Band Heater Heating Element
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. Nozzle band heaters are available in mica, ceramic, micro tubular and sealed type. Nozzle band heaters with inbuilt thermocouple are also available. We suggest micro tubular nozzle heater with inner brass bushing and outer SS strap for high temperature applications.
