Corning's ceramic substrates launched a global clean-air movement
Optimized for high performance, efficiency, and flexibility, our advanced ceramic substrates can meet the most demanding gasoline and diesel system needs in both light-duty and heavy-duty applications.
Corning® Celcor® substrates and Corning® Celcor® LFA substrates offer a proven track record of overall emissions reduction performance. And Corning® FLORA® substrates provide a path to further address the difficult to reduce cold-start emissions that occur just after a vehicle’s engine cold-start.
Within our Celcor® product families, standard-wall, thin-wall, and ultrathin-wall options can satisfy a variety of design needs. Standard-wall ceramic substrates can meet baseline requirements, while thin-wall products improve emissions performance and expand design options for advanced emissions control systems. Our ultrathin-wall options enable very high performance emissions systems that meet increasingly stringent regulations – high conversion, efficiency, and low pressure drop.
