Honeycomb Ceramic/Metal Substrate Catalyst for Auto Exhaust System Pt Pd Rh

Honeycomb Catalyst

As China’s leading supplier of catalysts, WEIFU has rich experience in the development of emission control technologies for a wide range of market applications that protect the air we breathe. Protecting the air from harmful emissions is the focus of innovative solutions within WEIFU. New engine technologies, tightening emission regulations and fluctuating precious metals prices create emissions control challenges. We help make our customers more successful with innovative, cost-effective solutions to meet the toughest emissions control regulations. Our mission is to reduce emission for a better living environment.

Since 1970s, cordierite ceramic honeycombs have been developed as substrates for automotive catalytic converters to solve the environmental pollution problems. This kind of substrates are also used in other fields because of their unique material and structural properties such as high porosity, low thermal expansion, high geometric surface area, and low gas flow restriction.

Metallic catalyst substrates are made of thin metal foils. The advantages of metal substrates are their high geometric surface area, low pressure drop and improved flow properties associated with the thin walls. The foils in metallic substrates can be brazed/welded together to provide good mechanical durability and resistance to thermal shock.

WFEC will give reasonable suggestions and solutions on the basis of customer demand.
