Medium-High Temperature Moisture-proof Magnesia Powder

Our Medium-High Temperature Moisture-proof Magnesia Powder is made of fused magnesium that contains more than 98% MgO and low Iron, firstly grinned, secondly preceded with high temperature calcinations, and thirdly added additives. The product has following features:

  1. Temperature resistance:excellent electrical performance, low leakage current under high temperature conditions, High safety,Has been widely applied to the high temperature electrical oven and toasters.
  2. Filling effect:Good flow properties, better density when filled into heat pipe, therefore good thermal effects.
  3. Silicone oil added, which has allowed good moisture resistance, so the heat pipes need not to seal the ends or anneal. Also, the production process is simple and low cost.
