Black Pigment Production
- LANXESS increases black pigment capacity
- Debottlenecking at the world’s largest plant for synthetic iron oxide pigments
As a leading supplier we have expanded the capacity for black synthetic iron oxide pigments at our Krefeld-Uerdingen site by more than 5,000 metric tons per year. The increased demand from the construction industry, in particular for our unique black pigments to color concrete, can be even better met with the debottlenecking measures that have now been completed.Thus, we are continuing the systematic expansion of our production capacities for synthetic iron oxide pigments. LANXESS is the only supplier worldwide to produce these pigments using the Laux process.
In Krefeld, LANXESS operates the world’s largest plant for manufacturing synthetic iron oxide pigments. The global importance of this site is confirmed every year by its extensive investment in capacity expansion and process optimization, as well as the continuous expansion of environmentally friendly production technologies. Thanks to the unique Laux process, the production facility at the Krefeld-Uerdingen site already has an excellent carbon footprint. This is because this special chemical process uses the heat generated during the reaction to create steam, which is in turn used in the subsequent process steps.
