Product Description

Catalyst carrier cordierite honeycomb ceramics for DOC

Ceramic honeycomb substrate (catalyst monolith) is a new kind of industrial ceramic product, as a catalyst carrier which are widely used in automobile emissions purifying system and industrial exhaust gas treatment system.

 

Catalytic converter substrate for vehicle:its major material is composed of cordierite and stainless steel of iron
The material for catalytic converter substrate is cordierite. The natural cordierite exists very rare in nature, so most of
cordierites are man-made substances. 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.
The usual CPSI for catalytic converter 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.
 

Benefits of Products:

1)Low thermal expansion coefficient
2)High porosity of hole on the wall , good liquidity and uniform distribution.
3)High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong.
4)The pressure drop is small.
5)Cold start performance is good, low light-off temperature, high conversion efficiency.
