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. The Fiberfrax® ceramic fiber paper product line is a unique family of products which is manufactured by forming aluminosilicate fibers in a nonwoven matrix. The ceramic fibers are randomly orientated during manufacture, then held in place with a latex binder system. A specialized paper-making process is statistically controlled to form uniform, lightweight, flexible sheets. Unifrax has been producing Fiberfrax® papers for over 25 years and is the largest ceramic fiber producer worldwide with in-house paper-making capabilities. By blending different fibers, binders and additives while varying the manufacturing process, Unifrax now produces a variety of Fiberfrax® paper products for a wide range of applications. Fiberfrax® papers exhibit excellent chemical stability, resisting attack from most corrosive agents. Exceptions are hydrofluoric, phosphoric acids and concentrated alkalies. If Fiberfrax® papers are wet by water or steam, all thermal and physical properties are completely restored upon drying. No water of hydration is present in most Fiberfrax® paper grades. Fiberfrax® papers have good dielectric strengths. Fiberfrax® papers, with the exception of the inorganic Series, will generate small amounts of smoke and trace element outgassing during the initial exposure to temperatures above 450 deg F. 970 paper is made from high-purity Fiberfrax washed fiber. During the manufacture of this product, a large portion of the unfiberized particles in the bulk fiber are removed prior to paper lay-up. The washing of the fiber gives great uniformity to the paper's structure while reducing weight and improving the thermal performance, in addition, this product is preferred in automatic die stamping operations where unfiberized particles in the paper can lead to excessive die wear.
