Fiberfrax® 6000 Series fibres are manufactured from kaolin clay rather than the high-purity alumina-silica raw materials in Fiberfrax 7000 Series fibres. Since kaolin is a mined material, it may contain impurities such as Fe2O3, TiO2 and Na2O. Even with these impurities, Fiberfrax 6000 Series fibres can provide an effective solution in many vacuum-forming and related applications.
Some of the unique properties offered by these fibres are:
Fiberfrax fibres are available in a variety of chemical compositions and diameters for use in a wide variety of applications. In addition, these fibres can be further modified by chopping or by removing the unfiberised particles (known as “shot”). Lubricants can also be added to the fibres to enhance their properties.
