Fiberfrax^® Ceramic Fiber Papers

Fiberfrax^® Ceramic Fiber Papers are a unique class of products which consists primarily of an alumino-silicate fiber in a non-woven matrix with a latex binder system. A specialized paper-making process is used to form uniform, lightweight, flexible sheets. By blending different fibers, binders, and additives while varying the manufacturing process, Unifrax Corporation now produces a variety of Fiberfrax paper products for a wide range of applications. 

Fiberfrax ceramic fiber papers are differentiated by thickness, density, fiber index, and chemistry. They are often segmented into three groups: 

• Utility grade: Rollboard paper, the most cost-effective product in applications where continuous performance characteristics is less critical. 
• Standard grades: 550 and 970 Papers are used where reliability and consistency are important. 
• Premium grades: 880, HSA, 882-H, and 972-H Papers are used either when organic out-gassing cannot be tolerated or when thermal performance is critical. “-H” designation references the heat-treating process used to remove organics. 

Unifrax has several manufacturing capabilities which can enhance the performance of Fiberfrax papers in a wide variety of applications.
