Ceramic Fiber Board
Aluminum silicate ceramic fiber board is processed by wet vacuum forming process. The strength of this type of productis higher than fiber blanket and vacuum forming felt, and it is suitable for high temperature fields, where the product has rigid strength requirements.
Application
Thermal insulation of high temperature equipment
Backing materials for industrial kilns
Heat insulation materials for heating device
Thermal insulation and fire-retardant materials for metallurgy, petrochemical, glass, ceramics, non-ferrous metals and other industries
