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.
Use: armored wire, armored heater.
It is used for high-power single-ended electric heating pipes and hot runners, etc. It has the advantages of insulation, pressure resistance, and good heat transfer effect.
