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 Fibers
- High-Temperature Fibers
- Large-Diameter Fibers
- Milled Fibers
Fiber 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 stability
- High-temperature frictional performance
- Fade resistance
- Flexural reinforcement
Fiberfrax 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 properties - Excellent high-temperature stability
- Good strength and high modulus
- Low coefficient of thermal expansion
- Superior chemical resistance
- Very low moisture absorption
The 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: - Mastics
- Adhesives
- Thick Film Coatings
- Fire Protective Materials
- Caulks, Putties, and Sealants
