| DESCRIPTION Cerafiber: Spun refractory fibres, made from electrically melted alumina and silica. Cerachem Fiber: Spun refractory fibres, made from electrically melted alumina, silica and zirconia. Cerachrome Fiber: Spun refractory fibres, made from electrically melted alumina, silica and chromia. All three fibres are resistant to chemical attack, except for hydrofluoric and phosphoric acids and strong alkalies. TYPE Bulk refractory fibres. MAXIMUM CONTINUOUS USE TEMPERATURE Cerafiber: 1260°C Cerachem Fiber: 1425°C Cerachrome Fiber: 1425°C The maximum continuous use temperature depends on the application. In case of doubt, refer to your local Thermal Ceramics distributor for advice. FEATURES - Excellent thermal stability: resist devitrification at high temperature - Low thermal conductivity - Excellent thermal shock resistance - High chemical stability - Contain no binders or corrosive agents - Resilient up to high temperatures - Low heat storage capacity - Excellent sound absorber - The packed density of bulk refractory fibres is between 90 and 200kg/m3 depending on the force applied to pack it. It is very difficult to obtain a density higher than 200kg/m3 by hand packing. |
APPLICATIONS:- Raw material for the manufacturing of finished products such as boards, paper, shapes, yarns etc - Loose insulating fill for complex spaces and areas where access is difficult - Packing expansion joints - Packing material for temporary repair of insulation - Fibre reinforcement for insulating concretes and |
