Material Notes:
Fiberfrax PH blanket is a unique product that has been specifically designed to provide excellent filtration capabilities in addition to the high chemical stability and low thermal conductivity that is possessed by all Fiberfrax products.PH blanket is made from Fiberfrax bulk ceramic fibers in a unique wet felting process which removes unfiberized particles. In addition to the strength and resiliency afforded by the interlocking of fibers during the manufacturing process, handling strength is further enhanced by the addition of a small amount of organic binder.A typical filtration application would involve utilizing PH blanket as a platinum catalyst recovery filter in nitric acid production. In this application, PH blanket offers numerous advantages over glass woll products including longer life, 50-60% improved filter efficiency, reduced chance of blowouts, and better temperature resistance.Typical ApplicationsCatalyst recovery filter in nitric acid productionDiffusion medium for fluidized bedsFiltration and catalyst carrier medium for radioactive particles and hot exhaust gasesInformation Provided by Unifrax I LLC
