K23/JM23 Mullite Insulation Brick
1.Excellent compression strength 2.Resistance to acid and alkali 3.Excellent heat stability and Low heat storage 4.Low thermal conductivity, high hot compressive strength 5.Resistance to High temperature, Resistance to erosion, resistance to abrasion 6.High alumina, low iron and alkali flux content
Brief Introduction
JM/K23 Insulation Brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM insulating brick is the new energy saving material for insulation. JM23 insulation brick are produced accordance with German industrial standard that especially for export to foreign countries.
