BIO-TEX packing type ECW/BIO
Packing Of ECW/BIO type is produced of yarn made of high quality biosoluble refractory fibres , designed for use at temperatures to 800 °C. As opposed to ceramic fibres, this material is not subject to any hygienic restrictions in the EU Member States in accordance with the Q note of Directive 97/69 EC. The used fibres are characterized by perfect thermal stability and keep their original structure to the amount of the maximum temperature of use. Products of BIO-TEX type do not contain refractory ceramic fibres (RCF) and asbestos. Ropes and packings of BIO-TEX type are intended for application in furnaces, flaps, hatches, cleanout openings and expansion gaps. Applied e.g. in power plants (coal mills), in cokemaking (coke batteries), founding (forms sealing), ceramic industry (ceramic carts and furnaces) and municipal economy (coal furnaces).
