Product Description

Honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. 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.

Catalyst Ceramics/Honeycomb Ceramic Substrate

Ceramic Honeycomb Substrate ate 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.

We can offer honeycomb ceramic substrate with different specification and differnt cars for the car converter as the customer requests. The ceramic substrate is made of cordierite, and it is used for car catalytic converter. The shape will be round, oval or racetrack. The major technical parameters for cordierite are as below:
*Thermal Expansion Coefficient: ≤ 1.45x10-6/ 20-800
*Absorption Rate: 20~30%
*Inner Wall Thickness: 0.20+0.02mm
*CPSI ( cell pieces per square inch): 200-600
*Crushing Strength: ≥ 14 MPa (on the top)≥ 4 MPa (on the side)
*Soften temperature: ≥ 1360

*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc, for instance, utilized in exhaust catalytic converter, airfresher machine for hotel, restaurant, toilet and so on.

*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
