Fiberfrax® Large Diameter Fibers

Fiberfrax® Refractory ceramic fibers are a family of high temperature fibers designed to be used in a variety of industrial and commercial applications. Manufactured from alumina-silica materials these fibers offer such characteristics as high temperature stability, low thermal conductivity, low heat storage, excellent thermal shock resistance, light weight, and superior corrosion resistance. Fiberfrax Refractory ceramic fibers exhibit thermal stability at temperatures up to 1260°C (2300°F).

Fiberfrax Refractory ceramic fibers are available in a variety of chemistries and diameters which can service a wide variety of applications. In addition, these fibers can be further modified by chopping or by removal of the unfiberized particles (called shot). Lubricants can also be added to the fiber to enhance fiber properties. Unifrax 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 the Fiberfrax® Spun Fiber and Long Staple Fibers. Average fiber diameters for these fibers range from 3 to 12 microns as detailed on the table below.

These larger-diameter fibers provide certain desirable properties, such as:

  • Excellent resistance to mechanical stress and vibration
  • Reduced processing time in vacuum-forming operations
  • Ability to produce lower-density vacuum-formed products
