400 CPSI High quality ceramic core catalytic converter substrate for automotive ceramic honeycomb filter air euro 4 catalytic

The necessary property of ceramic honeycomb catalyst substrate used in cars as follows:
1.High specific surface area: ensure exhaust gas could contact weigh catalyst enough.
2.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.
3.Warm up characters: after starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time.
4.Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it won’t affect the performance of engine.
5.High intensity: substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed.
6.Perfect assembly: substrates are parts of exhaust; perfect appearance and exact dimension could ensure assembly perfect.

Ceramic Honeycomb catalytic converter is a kind of effective molten metal filter. It’s three-dimensional connected mesh structure and high porosity has many advantages,par exemple, large surface area of slags collection,large inner surface area of filtering,small flow resistance,good filtering effect,etc.

The preferred catalyst support structure is a honeycomb configuration which includes a variety of unobstructed parallel channels sized to through gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.

Our Ceramic Honeycomb is made of cordierite, The cells density can be 100 cpsi, 300 cpsi , 400 cpsi or 600 cpsi. The usual cpsi (Cell Per Square Inch) for catalytic converter substrate is 400, the shape of ceramic converter substrate is round, racetrack,ellipse and other special shape according to the customer’s requirement.
