Product Details
Insulation ceramic fiber paper is a lightweight refractory material processed from a blend of high purity alumina-silica fibres into a highly flexible, uniform sheet. It is recommended for classification temperatures up to 1430C. made of a bulk ceramic fibre and organic binder. It is necessary for gaskets to be used in high temperatures due to their excellent workability and ductility.
