Description

The honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. The cells density can be **0 cpsi, **0 cpsi , **0 cpsi or **0 cpsi. The shape will be round, oval or racetrack. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals. Specification of catalyst carrier (straight hole) used in gasonline engine car. Channel Density: ******0 Holes/square inch Remark: If the channel density is within **0 holes/square inch, the shape diameter within **0***0 mm, and the height within **0 mm, we can customize the product according to the user&#**9;s requirement.
