Ceramic Fiber Board – vuulcanrefractory.cn

Description of Ceramic Fiber Board:

In addition to its hard texture, excellent toughness and strength, ceramic fiber board also has outstanding wind erosion resistance. Moreover, apart from being lightweight and not expanding when heated, it is convenient to install and easy to form or cut. It is an ideal energy-saving material for insulation equipment such as kilns and pipelines.
