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 uncoated noble metals.
We can supply 100CPSI, 200CPSI,400CPSI,600CPSI.
The ceramic substrate can be in the shape of round, racetrack and ovral.
Specification can be customerlized, as the the customers requirement.
The ratio of noble metals can be coated as per the customers emission standards:
Euro II, Euro III and Euro IV and EPA standard and the Cariforlia standards.
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
