Construction
Ceramic fibre woven fabrics are manufactured from high performance ceramic
fibres yarns reinforced with either a wire or glass filament. Ceramic fibre
yarns are produced on traditional textile machinery by carding high purity
1260°C grade ceramic fibres with a percentage of cellulose fibre to assist
in the processing. The yarns are then spun and combined with the relevant
reinforcing media to improve the tensile strength at extended temperatures.
The organic content will burn off at temperatures above 200°C without
affecting the properties of the ceramic fibre however adequate ventilation
should be provided during this initial heating. Where tensile strength is
important the temperature limitations of the reinforcing media should be considered.
Properties
Ceramic fibres are resistant
to oils, solvents and most chemicals although contact with phosphoric, hydrofluoric
acids, and strong alkalis should be avoided.
Are non combustible.
Have low thermal conductivity.
Suitable for use at temperatures
up to 1260°C dependant on application.
Colour: White.
