Production Description:

SCR--Selective Catalytic Reduction Catalyst For Vehicle


Application:MISCELLANEOUS

our company professionally produce various kinds of automobile catalysts, catalytic converters and mufflers , which are suitable for cars in all types and can meet the emission standard Euro2,3,4, EPA and CARB.

Our quality management system is ISO/TS16949.

On the surface of the cordierite or metallic substrate, coated with high surface area and good thermal stability washcoat with less precious metals such as platinum, palladium and rhodium, which are used for purifying of unburned hydrocarbons (HC) , carbon monoxide (CO) , and oxides of nitrogen (NO_X) form the internal combustion engine . The cells of honeycomb density can be 100,200,300, 400 or 600 cpsi and more. The shape will be round, oval, racetrack or other special .

The Features of our products:

1. Low thermal expansion.

2. High surface area.

3.Long-term durability performance.

4. Low pressure drop.

5. Good thermal shock resistance,

6. Combined with the EGR systems to help different vehicles to satisfy emission standard

7. Low light-off temperature

8. Excellent adhesion between wash-coat and susbstrate with netty structure
