Magnesium Oxide Powder High Temperature Meg

Magnesium oxide powder-high temperature MEG

The high temperature magnesium oxide powder adopts more than 98% fusing MgO powder as raw material. After crushing and grinding, adding proper additive, then fabricate it through high-temperature calcination.

1.Hight temperature resistance: excellent electrical performance, under high temperature, it has low leakage of current, high security, is widely used for heaters which used for dry heating.
2.High performance of filling: good flow property, can be more denser, good thermal effects.
3.Without silicon oil, greatly extend the life of heater under high temperature environment.
