About WPX Faserkeramik GmbH
WPX Faserkeramik GmbH develops, produces and sells high-performance components made of oxide fiber ceramic (WHIPOX) for industrial heat treatment and other high-temperature applications. The company was spun off from the German Aerospace Center (DLR) in Cologne, where the material was developed, among other things, for turbine components and heat shields. Production at the Troisdorf site covers the entire process chain: production of ceramic compounds, automated infiltration, CNC-controlled winding of high-performance fibers, machining of green bodies, drying, firing and finishing. Products include plates and grids as separation layers for loading racks as well as a 0.5 mm thin fiber-ceramic fire protection foil for e-car batteries, which withstands thermal runaway temperatures up to 1,200 °C and meets the UN standard GTR-20. Customers include plant manufacturers, suppliers to the automotive industry and companies such as Graphite Materials and Polynt. Since August 1, 2026, WPX has been part of the HKO Group in Oberhausen; brand, team and production remain in Troisdorf.
