Honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. Honeycomb ceramic substrate has a very competive substrate, we can produce 100CPSI, 200CPSI, 400CPSI, 600CPSI can be in the shape of round, racetrack and ovral. Size can be produced as per customer's requirements. It can be coated with the catalyst and the noble metal as per emission standards: Euro II, EuroIII, EuroIV and EuroV. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals.
Honeycomb ceramic substrate for vehicle major material is composed of cordierite, the usual CPSI for catalytic converter ceramic substrate is 400CPSI. The shape of honeycomb ceramic is round, racetrack, ellipse and other special shape as per customer's requirements. Our ceramic honeycomb an ideal catalyst substrate media for oxidation & reduction catalyst. Our typical substrate is available in a variety of sizes with the different shapes, such as: Round, elliptical, race track and so on.
Advantages:
*High specific surface area: Ensure exhaust gas could contact weigh catalyst enough
*Stable water absorption: Guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste for too thick coating
*Warm up characters: After starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time
*Low exhaust resistance: Ask exhaust resistance of substrate to engine low, so that it won't affect the performance of engine
*High intensity: Substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed
*Perfect assembly: Substrates are parts of exhaust, perfect appearance and exact dimension could ensure assembly perfect
