    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.TEZ-1 without Silicon Oil, is suitable for heater which is fabricated by hight temperature treatment. TEZ-2 and TEZ-3 with silicon oil, good moisture resistance, heater can be used directly without sealing. Production process is more simple and low cost.
