BP MULLITE REC
Sintered fused mullite 75% alumina
Made of fused mullite grains. Excellent creep resistance with vapour corrosion resistance at very high temperatures.
Typical application
BP MULLITE REC is dedicated to superstructure application. Due to its excellent creep resistance at very high temperature, BP MULLITE REC allows thicker insulation on crowns to reduce heat losses. Used in reinforcement and textile fiber glass furnaces as well as for vitroceramic and borosilicate glass furnaces.
If mortar is required, use BP MULLITE MORTAR.
