Application

Resource

Polycrystalline mullite fiberboard is formed by wet vacuum filtration and pressure with loose cotton and inorganic adhesive, and is calcined at high temperature according to different models; the product has the excellent characteristics of low bulk density and high strength, and is a multi-purpose product that can be used for hot surface of furnace lining to resist flame and direct impact of high-temperature airflow.

In addition to polycrystalline mullite fiberboard, we also supply polycrystalline mullite fiber blanket. Welcome to your Inquiry.
