Corning has been a leader in clean-air technologies since 1972, when our scientists invented the cellular ceramic substrate at the heart of catalytic converters.

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.
