Nebulox™ Cellular Ceramics – Range of Ultra-light, Fiber-free, Porous Refractories

on 18 April 2018


20180418 Nebulox Feuerfestkeramik 269Nebulox™ ultra-light porous refractories offers very low thermal conductivity for high temperature applications up to 1700°C. Produced from pure raw materials through a patented technology, Nebulox™ products are free from fiber and hence safe for health and environment. The unique porous structure offers excellent thermal shock resistance over a wide temperature range and can be easily machined to suit the specific applications. The Nebulox™ is available in two chemical compositions, in standard sizes up to 450 x 300 x 64 mm. Special sizes/chemistry can be offered on request.
