Description
Mica Band heaters are efficient and economical solutions to the heating requirements of many applications. Mica 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.
The Mica Band Heaters made by Vijay Heat’s utilizes different types of Top Grade Mica. The thickness of each mica layer is carefully selected in order to balance between the insulating characteristics of mica and the ease of heat transfer from the heating core to the machine barrel.
FEATURES
- Clamping straps will assure efficient heat transfer
- The low mass design allows quick heat-up and a quick response

- Ensure Heater ID same as OD of cylinder/nozzle
- Eliminate contamination of oil, plastic, dirt etc on cylinder surface to avoid carbonizing & shortening heater life
- Secure firmly to avoid Air gap and also to compensate for normal expansion, re-tighten periodically
- Maintain temperature controls & accessories in good working condition to avoid over heating condition
- Protects leads from abrasion
- Avoid process material leakage to terminal
