Ceramic fiber paper is produced by high purity ceramic fiber and applied in the higher temperature heat insulation field. The advanced produce technology make the fiber in uniform distribution, also, the thickness of density are controlled strictly. In the production process, a few of binder is added with scientific selection and strictly controland the binder can be burning out in the application process.PattonTek ceramic fiber paper with high density is a kind of fiber paper with high strength which is manufactured according to customer's demand. It is with excellent heat insulation property and easy to construction. Also, the ceramic fiber paper is easy to future process (multilayer composite and cut). Ceramic fiber paper with excellent high temperature resistance and heat insulation performance and good melt infiltration resistance,so it is very suitable for using as off isolation casting gasket in building and glass industry.
