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 heart 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.
