Our first foray into environmental clean-air technologies began when we invented the cellular ceramic substrate more than four decades ago, in order to help automakers meet U.S. Clean Air Act regulations. Today, we are as committed as ever to researching, developing, and engineering environmental technology products that improve the quality of the air we breathe.
We create ceramic substrates and particulate filters that form the core of world-class emission control systems – from light-duty passenger cars to heavy-duty trucks, and construction equipment. These emission control products deliver consistent, reliable, and durable performance under demanding conditions. Backed by a global network of service, engineering, and manufacturing facilities, we provide the quality products, market understanding, and dependable supply to help customers meet or exceed environmental regulations.
