Ceramic Honeycomb Substrate is the core product of our company. Their thermal expansion coefficient can be controlled within 1.1 × 10-6, the average diameter of poreis 8-10μ M, with the wall thickness of 0.15-0.17mm, achieving leading industrial level in China, and ready to be used in a variety of catalytic converter applications. Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit 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.
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.
*The 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
Cell density: 100-600 CPSI
Round, oval, racetrack
Euro II, III, IV
Ceramic Honeycomb Substrate:
*large specific surface area
*Low coefficient of the thermal expasion
*High thermal shock resistance
*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: After starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time
*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.
Oval Ceramic Honeycomb Substrate
*Oval ceramic honeycomb susbtrate mainly size: Below the length 170mm
*Oval Ceramic Honeycomb Substrate mainly application car: Mainly applicable to Nissan. Buick Excelle, Hongda, etc
