Rigid Ceramic Fiber Board

Product Overview

Featuring a dense structure, high strength, and good machinability, Rigid Ceramic Fiber Boards are widely used in various high-temperature industrial kilns, thermal equipment, and insulation systems. They are particularly suitable for applications requiring high dimensional stability and mechanical strength in insulation materials.

Product Structure and Manufacturing Process

The primary raw materials of ceramic fiber boards include high-purity alumina, aluminum silicate, and others. They are manufactured through a wet-process vacuum forming technique, followed by multiple steps such as drying, cutting, and polishing, resulting in a dense and smooth-surfaced rigid board. Certain products can incorporate reinforcing fibers, organic binders, or inorganic additives to enhance performance and application adaptability based on specific requirements.
