BenefitsCorning builds on more than 40 years of ceramic material and process knowledge with its fast light-off substrates. Through a unique material design that significantly reduces mass, FLORA® substrates can reach operating temperature more quickly than our standard Celcor® substrates to lower cold-start emissions. Discover best-in-class technical expertise from the company that invented cellular ceramic substrates and sets the standard for catalytic converters worldwide. • Excellent time to light-off performance to meet
stringent HC emissions requirements • Designed to facilitate on-wall coating to help maximize
catalytic performance• Can lower system cost by reducing precious metal use• Improves fuel efficiency
Fast light-off substrates significantly reduce cumulative hydrocarbon emissions compared to standard substrates.
