Polycrystalline Mullite Fibre Board

The fiber board is made by wet vacuum filtration and pressure forming, using loose cotton with organic and inorganic binders. This product has a hard texture and excellent strength, resistance to erosion, and is easy to process and cut. Its raw materials are chemically stable refractory fibers, making it lightweight and having good insulation properties. It is a versatile product, often used for furnace linings to resist flames and direct high-temperature gas flow impacts.

Overview

The fiber board is formed by the wet - method vacuum suction filtration and pressure - forming process. It is made of loose cotton with a combination of organic and inorganic binders. The classification temperature of this product ranges from 1200°C to 1900°C.

Product nature

High temperature stability, low thermal conductivity, low thermal capacity; thermal shock and erosion resistance; easy to process and cut; good resistance to flame and gas flow erosion; precise thickness and dimensions, easy to install and use.

Furnace lining and insulation use

Polycrystalline Mullite Fibre Board is used as rigid furnace lining board, backup insulation, heating chamber panels and machined parts for industrial furnace linings.
