Magnesium oxide powder-high temperature Magnesium oxide powder-Middle temperature Magnesium oxide powder-Low temperature

Magnesium oxide powder-Low temperature MED

The low temperature magnesium oxide powder adopts more than 93% 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 low temperature, it has low leakage of current, high security, is widely used for heaters of home appliance.

2 High performance of filling: good flow property, can be more denser, good thermal effects.

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