High-Density Ceramic Fiber Board

Product Overview

High-density ceramic fiber boards are manufactured from high-purity refractory fiber materials, featuring a dense structure, high strength, superior high-temperature resistance, exceptional thermal insulation, and excellent thermal shock and erosion resistance. They are widely used for thermal insulation in industrial furnaces, pipelines, and equipment, offering easy installation and significant energy-saving benefits.

Product Structure and Manufacturing Process

High-density ceramic fiber boards are made from core materials such as high-purity alumina and silica, processed into continuous fiber wool. Using vacuum forming technology with specialized inorganic binders, they undergo precise ingredient mixing, uniform blending, molding, low-temperature curing, and edge trimming. Their dense layered structure ensures no voids, with evenly distributed binders, guaranteeing high strength and stable low thermal conductivity.
