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 FibersFiber index is a measurement which determines the amount of fiberized material in the actual fiber. During fiber manufacturing, shot or unfiberized materail is produced as a natural product of the fiberization process. Unifrax has the ability to reduce the amount of shot in a fiber by controlling the furnacing process or by washing out the unfiberized material. Fiberfrax High-Index have proven to be a good reinforcement material for use in automotive break lining and other friction material. These high-index fibers provide a variety of desirable properties such as:Frictional stabilityHigh-temperature frictional performanceFade resistanceFlexural reinforcementFiberfrax High-Index fibers can also be used as a mechanical thixotrope in coatings applications offering reinforcement and fire resistance as additional benefits. These fibers offer the following unique propertiesExcellent high-temperature stabilityGood strength and high modulusLow coefficient of thermal expansionSuperior chemical resistanceVery low moisture absorptionThe thixotropic properties of Fiberfrax High-Index Fibers in conjunction with the mechanical and physical properties they have to offer make them an excellent candidate for use in:MasticsAdhesivesThick Film CoatingsFire Protective MaterialsCaulks, Putties, and SealantsInformation Provided by Unifrax I LLC
