Types of Band Heaters.
Mica Band Heaters are ideal for customization. They have a high watt density due to their tightly clamped thin resistance ribbon between pieces of mica.
Ceramic Band Heaters have a high temperature capacity of 1200⁰F. Although they are more expensive to make, they typically have the longest span due to the coiled resistance wire being fed through knuckles (ceramic blocks).
Rectangular Heater Bands are used to apply the maximum amount of heat to a specific area. Due to the rectangular enclosure, heat is easily kept and more efficiently used. This type of band heater also heats the fastest.
