Magnesium Oxide insulator for heaters

The magnesium oxide insulator is used for the cartridge heater, the sheathed heater, and the glow plug, because the magnesium oxide is superior in the electric insulation characteristics. The magnesium oxide insulator is used as an insulated core that wraps an exothermic wire and as a guide insulator that guide a metal wire. We can produce the magnesium oxide insulator of various purities and various densities(=strength).
