Ultrafine ceramic fiber board is a plate-like material formed by ultrafine ceramic fiber cotton through a special double-sided needling process. Utilizing a precise proportion of binding agents and processed through advanced automatic vacuum absorption machinery and specialized drying techniques, it results in a superior thermal insulation solution.
Ideal for exterior wall insulation in construction; backing thermal insulation for cement and building materials; kiln backing in petrochemical, metallurgical, ceramic, and glass industries; non-ferrous metal industry backing; and high-temperature reaction equipment linings.
