Honeycomb ceramic substrate is a component of environmental protection device in automobile exhaust system. Its main function is catalytic conversion substrate and particle filter for automobile exhaust emission control. As the substrate of automobile exhaust emission purification, honeycomb ceramics play a very important role in environmental protection and the healthy development of automobile industry.
inquiryThe honeycomb ceramics used in the automobile exhaust system to coat catalyst or capture particles are called ceramic honeycomb substrate, which is mainly divided into the straight-through carrier and wall-flow carrier.
Straight through a carrier: SCR carrier, Doc carrier, ASC carrier, and TWC carrier;
Wall flow carrier: DPF carrier, GPF carrier
Our Company can provide honeycomb ceramic substrates with coated and uncoated. The shape of honeycomb substrate can be round, oval, or racetrack.
After the catalyst is coated, the honeycomb ceramic substrate is applied to the catalytic converter to convert harmful emissions into water vapor, carbon dioxide, etc.
