Ceramic Fiber Cloth is woven from ceramic fibre yarn on specialized looms. CFC is suitable for temperatures upto 1260oC and typically used as high temperature curtains, gaskets or simply a wrap to reduce heat loss from a high heat generating equipment.
CFC can be pre-inserted with SS 304 to improve its tensile strength at elevated temperatures and it can also be coated with vermiculite or silicon rubber to make it 100% non-permeable. This makes it suitable for application in expansion joints and food industry.
Ceramic Fibre, which is used in weaving CFC majorly contains Aluminium Silicate
It is chemically composed of the following:
Al2O3 (47-49%) & Al2O3 + SiO2 (99%) - 85% (By Weight)
Viscose Rayon, Fibreglass Yarn - 15% (By Weight)
(Note: The Viscose Rayon present in Ceramic Fibre is the binder or the organic carrier, which smokes out at 250oC, causing a shrinkage of 12-13% in weight. This is referred as Loss on Ignition, which is an important technical parameter determining the quality of Ceramic Fibre)
