Corning ceramic substrates launched a global clean-air movement. Optimized for high performance, efficiency, and flexibility, our advanced substrates can meet your most demanding gasoline and diesel system needs in both light-duty and heavy-duty applications.

Our Celcor® and Celcor® LFA substrates offer a proven track record of performance, while our new FLORA™ substrates provide a path to reduce the dangerous cold-start emissions that occur just after a vehicle’s engine starts, without extra fuel or more precious metal.

Within our Celcor® product families, standard-wall, thin-wall, and ultrathin-wall options can satisfy a variety of design needs. Standard-wall 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—think high cell densities, efficiency, and extremely low pressure drop.
