Used by automotive OEMs and catalyst companies. Applicable for diesel vehicle exhaust upgrades, replacement parts, and non-road machinery emissions control.
Diesel Engine Exhaust Substrates：
Selective Catalytic Reduction System Carrier (SCR) / Oxidation Catalytic Converter (DOC):
This product is made of cordierite material, which is a core component that ensures the engine exhaust meets emissions standards. It has advantages such as a large specific surface area, high compressive strength, a low coefficient of thermal expansion, and good thermal shock resistance. It is used in the catalytic converters of diesel engine exhaust after-treatment systems to catalytically convert and purify harmful substances in exhaust gas, in order to meet various stringent emission standards both domestically and internationally. The performance of the product is at an advanced level in the country, and it possesses the capability for continuous optimization and upgrading for sustainable development.
