Medium temperature MgO Powder
Medium and high temperature electrical grade magnesium oxide powder
It belongs to the high temperature and moisture proof level electrical grade magnesium oxide powder, the product is treated by silicone oil, mainly used in high temperature air burning electric heating components, but not suitable for 1050℃ furnace process, mainly used in oven pipe, mosquito coil pipe and water heater pipe. The product load generally does not exceed 9W / cm² .
Excellent temperature durability: It has excellent electrical properties, characterized by minimal leakage current at moderate temperatures, ensuring unparalleled safety. This makes it an indispensable component in medium temperature heating applications.
Optimized filling efficacy: It has excellent flow properties designed to achieve greater density, which is further enhanced by its impressive thermal conductivity.
