Saffil^® Fibers

Saffil^® Alumina Fibers are high-purity polycrystalline fibers designed for use in applications up to 1600°C (2912°F). Since their development in the early 1970s, Saffil Fibers have been used successfully to solve problems in demanding high-temperature insulation and many other specialty applications.

Saffil Fibers are produced by a unique solution extrusion process which ensures the highest levels of chemical purity and lowest possible levels of shot content (non-fibrous particles). The unique method of manufacture allows the fiber diameter to be strictly controlled with a median of approximately 3 microns with very low levels of fiber less than 1 micron in diameter.

Typical applications:

• Saffil Fibers are used to increase the maximum use temperature in module, board, vacuum formed shape and paper manufacture.
• The fiber can be further treated by milling for more specialist applications.
