  • Details
    • Commodity name: Polycrystalline Mullite Fiber Veneer Block

    The product does not contain any binders or other ingredients, has excellent elasticity and flexibility, and the maximum operating temperature can reach 1600℃.

    Product Description

    Polycrystalline mullite fiber veneer block is made of polycrystalline mullite fiber cotton, compressed and cut by a special process. The product does not contain any binders or other ingredients, has excellent elasticity and flexibility, and the maximum operating temperature can reach 1600℃.When polycrystalline mullite fiber veneer blocks withstand this temperature for a long time in an oxidizing atmosphere, a neutral atmosphere, or a partial reducing atmosphere, they can still maintain their original toughness, strength, and fiber structure.The product does not contain slag balls and can be used for pasting the hot surface lining of various high-temperature industrial kilns. It has excellent thermal insulation properties and is currently one of the ideal high-temperature kiln liners.

    Product Features
