  • INQUIRY


This series of High Alumina Poly Light Insulation Bricks are sintered mainly with superior bauxite and proper additive, and then shaped by pressing and fire under high temperature. This kind of products is widely used for lining and heat insulation layer of industrial furnaces and kilns in metallurgy, machinery, ceramic, chemical industry, and so on. They are also an ideal energy saving product and are recommended to use below 1400.

Advantages

High Alumina Poly Light Insulation Brick has the advantages of high intensity, low thermal conductivity, small reheat linear change, excellent thermal stability, outstanding erosion and corrosion resistance.
