Ceramic Honeycomb Substrate
Honeycomb ceramic is new developed ceramic part. Because of it's features of corrosion resistances, large specific surface area, small heat resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. Honeycomb ceramic substrate is made of cordierite enjoys the merits of very low thermal expansion coefficient, high specific surface area, low pressure drop, rapid light-off and unique structures which are perfect for car catalytic converter. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals. The shape will be round, oval or racetrack with 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi cells that provide high surface for the precious metal catalysts that convert noxious emission into water vapor, carbon dioxide and so on.
Honeycomb ceramic substrate have a very competive substrates.
*We can produce 100CPSI, 200CPSI, 400CPSI, 600CPSI can be in the shape of round, racetrack and ovral.
*Specification can be customerlized, as the the customers requirement.
*Can be coated with the catalyst and the noble metal as the customers emission standards: Euro II, EuroIII and EuroIV and EPA standard and the Cariforlia standards.
Advantages:
*High specific surface area: Ensure exhaust gas could contact weigh catalyst enough
*Stable water absorption: Guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it is no waste for too thick coating
*Warm up characters: Ask exhaust resistance of substrate to engine low, so that it will not affect the performance of engine
*Low exhaust resistance: Ask exhaust resistance of substrate to engine low, so that it will not affect the performance of engine
*High intensity: Substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed
*Perfect assembly: Substrates are parts of exhaust; Perfect appearance and exact dimension could ensure assembly perfect
