1. Made of 409 stainless steel material, sturdy and durable, with good corrosion and high temperature resistance.
2. Coating precious metals for good purification performance.
3. Suitable for various vehicle models, sizes and standards can be customized according to needs.
4. There are multiple models to choose from.
Catalyst active ingredients:
Palladium Pd - the main component of catalytic nitrogen oxide reduction reaction
Platinum Pt -mainly plays a catalytic role in the oxidation reaction of carbon monoxide and hydrocarbons
Rhodium Rh - catalytic oxidation of carbon monoxide and hydrocarbons
Co catalyst (cerium, lanthanum and other rare earth elements) - it has no activity or very little activity, but can improve the performance of active components (activity, selectivity and stability).
1. Round & Oval metallic substrate for On-road vehicle.
2. Metallic substrate for small engine.
3. Metallic substrate for Off-road vehicle.
4. Metallic substrate for industrial catalyst.
5. Specific structure metallic substrate for other application.
