In 1942, one of our own research scientists, J.C. "Charlie" McMullen, discovered a method for attenuating molten droplets of alumina-silica into ceramic fibers, thus inventing ceramic fiber which was trademarked under the Fiberfrax® name over 50 years ago. The key technology in the production of Unifrax ceramic fiber products is the fiberization of the molten ceramic. This advanced process is the result of more than five decades of experience in refining and processing technologies developed by Unifrax engineers. The fiberization process takes place at our New Carlisle, Indiana facility using computer-controlled furnacing technology. Our proprietary process allows an extremely high degree of precision in the control of fiber dimensions which is critical to the final product characteristics. .
