Magnesium oxide powder-Middle temperature MEZ

The middle temperature magnesium oxide powder adopts more than 97% 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 middle temperature, it has low leakage of current, high security, is widely used for heaters of middle temperature.
2.High performance of filling: good flow property, can be more denser, good thermal effects.
3.MEZ-1 without silicon oil, is suitable for heater which is fabricated by hight temperature treatment. MEZ-2 and MEZ-3 with silicon oil, good moisture resistance, heater can be used directly without sealing. Production process is more simple and low cost.
