Saint-Gobain’s silicon carbide (SiC) diesel particulate filter (DPF) features high porosity. The SG4 offers SiC robustness that provides high thermal stability, severe regeneration, and corrosion resistance. With 60% porosity and narrow pore size distribution, the company’s microstructure is designed specifically to accommodate high washcoat loading with low impact on backpressure. Designed for DeNOx function integration onto DPF substrate, the SG4 takes advantage of highly conductive SiC and narrow pore size distribution. This catalytic function integration allows additional packaging benefit and downsizing potential for the full exhaust system. The SG4 is available with Saint Gobain’s asymmetric cell design and offers fuel economy optimized technology due to low backpressure, high soot loading operability, and increased regeneration interval. Cell density is available up to 300 cpsi. Saint-Gobain’s assembling design and manufacturing process allow production of substrates for any geometry and shape.
