Exhaust Honeycomb Ceramic Substrate Catalyst

Honeycomb Ceramic Catalyst Description:

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 material for catalytic converter substrate is cordierite. The natural cordierite exists very rare in nature, so most of cordierites are made substances. The major features for such cordierite are low thermal expansion coefficient, good thermal shock resistance, high anti-acid, anti-alkali and anti-erosion function and good mechanical strength. The usual CPSI for catalystic converter substrate is 400. The shape of honeycomb ceramic can be round, racetrack, ellipse and other special shape according to the customer's requirement in order to meet the different cars models requirements. Ceramic Honeycomb Substrate could be coated with noble metals as per customers requested emission standard: EuroIV or EuroV.

According to different requirement of exhaust-gas control, selecting high efficient ceramic substrates of various kinds. Our company is one of the national standard setters of cellular ceramic, we supply the core technologies on lowering thermal expansion coefficient, improving the cellular structure and wall thickness. We offer more than 40 sizes of ceramic substrate with various cell designs.
