Insulating Ceramic Magnesium Oxide Ceramic Insulated Tubes Magnesium Oxide Tubes for Cartridge Heaters
Product Description







Magnesium oxide rod:
We use high pure fused magnesia as raw material,made by high-pressure automatic extrusion and fired in a 1700-degree tunnel pushing plate cellar furnace with high density (2.3g /ml). The level of its insulation and withstand voltage products has been continuously improved.
Currently we can produce various kinds of single-hole, double-hole, four-hole, five-hole, six-hole, eight-hole, and nine-hole
porous magnesium oxide tubes with an outer diameter of 2.0mm-25mm,and we can also produce according to customer requirements.
Advantages:
* High temperature capability.
* Low electrical conductivity.
* High thermal conductivity.
* Good corrosion resistance.
* Infrared transparent
Usage:
* Heating elements
* Thermocouple tubese
* Armored wire, armored heater.
