Electro-Fused Magnesium Oxide for Electrical Heater
Electro-fused magnesium oxide used for insulating filler of heating elements.
Features
Electro-fused magnesium oxide is used for insulating filler of tubular heating elements.
To produce a tubular heating element, the coiled electric wire is inserted into the metal tube and the electro-fused magnesium oxide powder is filled into the inside gap.
Tubular heating elements are widely used for such applications as household appliances (electrical rice cookers, irons, hotplates, etc) and industrial equipment (molding machines, hot sealers, etc).
Electro-fused magnesium oxide powder plays a role in insulating the electric current running through the wire and effectively conducting only the thermal energy to the tube.
Our subsidiary, Tateho Chemical Dalian Co.,Ltd produces such electro-fused magnesium oxide grades, using electro-fused raw material made in China.
