catalyst ceramics

The material for catalyst ceramics is cordierite,The major features for such cordierite are low thermal expansion coefficient, good thermal shock resistance, high anti-acid, anti-alkali and antii-erosion function and good mechanical strength.high specific surface area, low pressure drop, rapid light-off time and reliable & durable performance are achieved through high cell density of 400 CPSI;

The usual CPSI for catalytic converter substrate is 400. At present, our typical substrate are available in a variety of sizes with the different shapes, such as: round, oval, race track and so on. according to the customer's requirement in order to meet the different cars models requirements.

Detailed Product Description:

 1. our company can offer honeycomb ceramic substrate with different specification and differnt cars  for the car converter as the customer  request.

 2.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:

1. Thermal Expansion Coefficient: ≤1.45x10-6/ 20-800

2. Absorption Rate: 20~30%

3. Inner Wall Thickness: 0.20+0.02mm

4. CPSI ( cell pieces per square inch) : 200-600

5. Crushing Strength: ≥14 MPa (on the top)≥ 4 MPa (on the side)

6. Soften temperature: ≥1360
