Our company customizes various magnesia tubes (round, square, flat, multiholes threaded types) for electric heating element manufacturers. The raw material is 99% fused magnesia of electric grade, which is automatically extruded under high pressure and sintered in a 1700-degree tunnel furnace, high density (2.3g/ml). Its insulation and withstand voltage performance are close to the level of similar products in the United States and Japan.
Outer diameter:1.8mm-25mm, annual output:200 tons.
The Magnesium Oxide Insulator is used for cartridge heater, sheathed heater, thermocouples, glow plug, etc. They can be made by dry pressing or injection moulding. The magnesium oxide insulator is used as an insulated core which is wrapped by Resistance Wire.
Magnesium oxide is both an excellent electrical insulator and a very good thermal conductor. These properties are appreciated in the thermal industry as a component of thermocouples and heating systems. Magnesium oxide can be used for a lot of metals compared with aluminum oxide.
We can supply magnesium oxide insulator of various purities and various densities (or strength), various shapes and sizes which makes the production of electric heater much easier.
The Magnesium Oxide insulators are carefully handled during storage and transportation to preserve the quality of our product in its original condition.
