Low High Temperature Magnesia Powder MED
Our low High Temperature Magnesia Powder is made of fused magnesium that contains more than 93% MgO, firstly grinned, secondly proceeded with high temperature calcinations, and lastly added additives. The product has following features:
- Temperature resistance：excellent electrical performance, low leakage current under low temperature conditions, and has been widely applied to the low temperature heating elements, mostly civil use.
- Filling effect：Good flow properties, better density when filled into heat pipe, therefore good thermal effects.
- MED-1Product MED-1 does not have Silicone oil added; hence it is suitable for high temperature treated heating pipe.
