ISOWOOL ceramic fibers are lightweight and it possesses excellent refractory and insulating properties. It is designed for a wide range of applications such as steel, non-ferrous, petrochemical and ceramic manufacturing industries. It is applicable to high temperature insulations ranging from 1000℃ to 1700℃. Using electrically melted highly purified materials, those fibers are formed by the air-blown method, having excellent refractory and insulating properties.
