Ceramic Fibre Products

Ceramic fibre is an asbestos free blown or spun alumino-silicate fibre made from blends of high purity alumina, and silica. A unique combination of physical and refractory properties makes this an outstanding material for use in high temperature applications. The basic fibre, which is white and non-crystalline, can be converted into a wide range of product forms to suit many different applications throughout the broad spectrum of industry particularly where hot processes are involved.

Key Properties

Key Properties of all Cerafiber, Cerablankets and Ceramic Fibre products are

    • Very low thermal conductivity - about one third that of insulating refractory bricks, meaning thin but effective insulation.
    • Extremely low heat storage due to low density. In furnace applications this means faster heat up and cool down times, hence higher productivity and fuel savings.
    • Light weight - one sixth the weight of insulating bricks. Fumace steel structure is hence much lighter, and costs less.
    • Easy to install and maintain, saves time.
    • Resistant to thermal shock. No matter how fast they are heated or cooled, the product forms
      will not crack or spall.

Good acoustic properties enable Ceramic Fibre Products to be used for noise reduction in high temperature enviorments. An attendant benefit is vibration reduction.

Ceramic Fibre is chemically pure, and has very low chloride content. Special handling techniques can be employed to further limit leachable chloride levels to less than 10 ppm, for use in contact with stainless steel in special applications.

Ceramic Fibre are compietely inorganic and binder free. Bulk fiber, blanket and moist felt, are therefore incombustable. Vacuum formed products contain a small quantity of temporary inorganic binder which burns off in service.
