Specification of Ceramic wooll 25mm - 50mm ( 085782614337 )
Ceramic fiber blankel is made from high quality Gao-Ling clay, high purity alumina and silica oxides by spun or blown process. It is asbestos free. No chemical binder is added. Double side needling provides blanket with great tensile or handling strength for easy inslallation. Blankets are available in various classified temperatures from 1260°C to 1430°C. Ceramic fiber blanket is resistant to most chemicals attack except hydrofluoric, phosphoric acid and high pH a kali (Na2O or K2O). Its thermal and physical properties can not be affected by oil, steam and water
Advantages
Heat resistance, Light weight, Low thermal conductivity, Low heat storage, Flexible, Resilient to thermal shock, High tensile strength, Corrosion resistance, Easy to install, Asbestos free.
Applications
Petrochemical process heater refractory fiber lining Heat treating furnace or intermittent (shuttle) kiln hot face lining General furnace backup lnsulation Heat seals for kiln car or furnace door Electrical insulator High temperature acoustic File protection
