Material Notes:
In addition to Fiberfrax Bulk Fibers, Unifrax has the ability to produce many different specialty fibers that provide a variety of desirable performance properties for certain applications. These fibers can be classified into the following general categories:High-Index FibersHigh-Temperature FibersLarge-Diameter FibersMilled FibersUnifrax has the ability to control the average fiber diameter of fibers through a unique spinning operation. It is this spinning operation that is used to produce both th Fiberfrax Spun Fiber and Long Staple Fibers. Average fiber diameter for these fibers range from 3 to 12 microns. These larger-diameter fibers provide certain desirable properties, such as:Excellent resistance to mechanical stress and vibrationReduced processing time in vacuum-forming operationsAbility to produce lower-density vacuum-formed productsInformation Provided by Unifrax I LLC
