Ceramic fiber paper, has low shrinkage, good handling strength, and low thermal conductivity. it contains a small amount of organic binder for processing which makes it flexible, yet reduces off-gassing and odour during use. our product has a highly uniform structure due to its controlled basis weight and thickness, assuring homoaeneous thermal conductivity and a clean, smooth surface ideal for gasketing or sealing.
Laurel ceramic fiber paper, is a lightweight refractory material processed from a blend of high purity alumina-silica fibers into a highly flexible, uniform sheet. It is completely free to asbestos and is designed to be an economic replacement for asbestos paper in most applications.
