Honeycomb ceramic substrate is a new kind of catalyst carrier, which is widely used in automobile emissions purifying system and industrial exhaust gas treatment system.After coating with catalysts, this product is applied in catalytic converter of diesel or gasoline vehicle to catalyze , convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV and Euro V. We also supply Catalytic Converter, Catalytic muffler, Motorcycle catalytic converter, DOC Catalyst, SCR catalyst ,Ceramic honeycomb monolith , metal honeycomb carrier, ect. Our management system has been certified the ISO9001 and TS16949 by SGS company.
We can supply both ceramic element coated with noble metals of Pt,Pd,Rh and ceramic element without noble metals
Advantage of Honeycomb Ceramic Substrate
- Thin wall, high Surface area.
- Low coefficient of thermal expansion.
- Low back pressure, good air flow.
- Good thermal shock resistance and heat resistance.
- High temperature resistance and chemical corrosion resistance.
- High compressive strength and stable water absorption rate.
- Accurate size control,good for encapsulation.
- Low light off temperature and high conversion efficiency.
- Ideal matching with different catalysts.
