1. Mica Band Heater Brief Introduction

 Mica band heaters are the ideal solution for high watt densities and high operating temperature applications, especially for the plastics industry. Band heaters can be found in several types of dimensions, wattage, voltages and material. It is an inexpensive form of heating solution to external indirect heating. And strip type is also very popular. Band heaters use electric heating (NiCr 2080 wire) to heat-up the external surface of drums or pipes and high quality mica material insulated.

Mica Band heaters are constructed with a mica core wound with wire. The core is then bent into a circle band. Leads are attached before the final outer sheaths are attached to complete the heater.

4. Mica Band Heater Application

Band heaters are commonly used in the plastics industry: to heat plasticization cylinders, extruders and injection presses. They are also employed on woodworking machinery and scientific-medical equipment.

Flat mica bands are used in the packing trade (sealing bars and wheels), industrial ironing (mangles) and plastics (extrusion/blower machines).
