Customized Low Shrinkage Ceramic Fiber Refractory Paper For Gasketing, Sealing

Description:

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.

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.

Ceramic fiber paper is completely free to asbestos and is designed to be an economic replacement for asbestos paper in most applications.
