OMM Heating Elements provide good quality Mica Band Heaters

The Mica Band Heater designed by OMM Heating Elements is a reliable Mica Insulated Band Heater that can perform at the higher operating temperatures [up to 900°F (482°C)]. It provides durable and efficient service. These Heaters are economical solutions to the heating requirements of many Applications.
Resistance wire ribbon, used in the Mica Band Heater is not restricted to the potential of Nichrome wire. Various alloys are considered for a variety of applications.

The external metallic protective sheath of our Mica Band Heaters, made of a special alloy which expands less than the barrel when heated. The thickness of each Mica layer is attentively selected to maintain a balance between the insulating characteristics of Mica and the facility of heat transfer from the heating core to the Machine Barrel.

Mica Insulated Band heaters can attain a maximum sheath temperature of 900°F, but with different electrical termination styles, clamping mechanisms, and ability to accommodate holes and cutouts, Mica Band Heaters are successfully used in many Applications, but are mostly sought for in the Plastics Industry.

To maximise the surface-to-surface contact, our Mica Band Heaters are carefully rounded and formed to optimise the grip on a machine barrel. This difference in thermal expansion makes the Heater grip the Barrel firmly once it is energised. This improves heat transfer which extends the life of the Mica Band Heater.
