Doc DPF SCR Honeycomb Cordierite Ceramic Catalyst Substrate for Car Exhaust Systems-安徽美程化工有限公司校园招聘简章

Product Introduction

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.

Honeycomb ceramic is used as DOC, SCR and DPF substrate. It features higher cpsi, thin wall and higher specific surface area, etc. After being coated with precious metal, it is applied to diesel and gasoline exhaust system and industrial gas treatment. We make customized production based on your specification.
