Cordierite DPF/GPF
This product is made of cordierite, which is a special structure of wall-flow cellular ceramic filter body with the advantages of high porosity, large specific surface area, low back pressure, small coefficient of thermal expansion, good thermal shock resistance, etc. It is applied in diesel exhaust purification device to utilize the pores on the pore wall of the wall-flow filter body to intercept and capture carbon smoke particles in the diesel exhaust and purify the diesel vehicle exhaust gas.
