Ceramic Fiber Board
EPOWOOL® Ceramic Fiber Board

EPOWOOL® Ceramic fiber board is a high temperature rigid product manufactured by a wet forming process using fiber bulk and binders. It offers low thermal conductivity and high temperature stability in application where vibration, mechanical stress and strong erosive forces are present. The excellent rigidity and modulus of rupture inherent to these boards makes hem strong and self-supporting, yet relatively lightweight and easy to cut or machine.
EPOWOOL® Ceramic fiber board can be used in a wide range of applications, such as thermal insulation, particularly in areas of fire protection and in domestic applications which have high requirement of environment friendly.
