Typical application

BP MULLITE is dedicated to superstructure application. Due to its high creep resistance at very high temperature, BP MULLITE is used in crowns and feeder covers for reinforcement and textile fiber glass furnaces as well as for vitroceramic, borosilicate and sodium silicate glass furnaces.

For very heavy insulation crown application, refer to BP MULLITE REC.

If mortar is required, use BP MULLITE MORTAR.
