Ceramic Honeycomb Substrate Introduction:
Ceramic Honeycomb Substrate is made of cordierite enjoys the merits of very low thermal expansion coefficient, high specific surface area, low pressure drop, rapid light-off and unique structures which are perfect for car catalytic converter. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals. The shape will be round, oval or racetrack with 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi cells that provide high surface for the precious metal catalysts that convert noxious emission into water vapor, carbon dioxide and so on.
The gasoline engine tail gas purifier carrier coated with catalyst is suitable for and is currently one of the most important means to control tail gas purification for gasoline engine discharge of tail gas in motorized vehicles. Our honeycomb
Ceramics are characterized by unique honeycomb structure, low expansion coefficient, good thermal stability, large specific area and low pressure loss, and reach domestic advanced level.
The usual CPSI for honeycomb ceramic substrate is 400. The shape of honeycomb ceramic is round, racetrack, ellipse and other special shape according to the customer's requirement in order to meet the different cars models requirements. High specific surface area, low pressure drop, rapid light-off time and reliable & durable performance are achieved through high cell density of 400, 500 and 600 cpsi. All of these make our ceramic honeycomb an ideal catalyst substrate media for oxidation & reduction catalyst. Our typical substrate are available in a variety of sizes with the different shapes, such as: Round, elliptical, race track and so on.
