Cordierite Honeycomb Ceramic Catalyst Doc SCR Catalyst Support Ceramic

Product Description

Product Description

Honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals.

Honeycomb ceramic is used as DOC, SCR and DPF substrate. It features higher cpsi, thin wall and higher specific surface area, etc. After being coated with precious metal, it is applied to diesel and gasoline exhaust system and industrial gas treatment. We make customized production based on your specification.

Features of catalytic converter ceramic substrates:

* Environmental-friendly
* Wear-resistant, long lifespan
* Main raw material: cordierite ceramic and is the key component of three-way catalytic converter.
* High temperature resistance;
* High mechanical strength;
* 100cpsi, 200cpsi, 300cpsi, 400cpsi, 600cpsi;
* Shape can be round, racetrack, oval, square based on request;

Application of catalytic converter ceramic substrates:

* Substrate for gasoline / petrol fuel engine exhausting system
* Substrate for diesel fuel engine exhausting system
* Substrate for air filtering;
* Substrate coated with precious metal (palladium, platinum and rhodium) to make catalytic converter. It removes harmful
chemicals of automobile exhaust purification system, such as HC, CO, NOX. It can meet Euro I, Euro II, Euro III, Euro IV and Euro V standard.
