Micro heater

Micro-heater is a heater with high electrical insulation and good thermal conductivity by tightly filling narrow tube (sheath) and heating wire with high-purity magnesia powder. It is also a highly reliable heater that is flexible and durable due to proper annealing processing.

Features

  1. Finished diameter is small, flexible, and easy to process
  2. Easy setting of heater capacity
  3. Excellent electrical resistance and insulation resistance, and good stability
  4. Since the heating wire is insulated from the atmosphere, it has relatively long life due to less oxidation and corrosion.

Use

  • For piping
  • Liquid crystal, plasma, etc.
  • Organic EL
  • Semiconductor/wafer
