Founded in July 2024,As China Silicon carbide DPF catalyst Suppliers and Wholesale Silicon carbide DPF catalyst Factory, Longyou Shuochun New Material Technology Co., Ltd. is a high-tech enterprise specializing in the coating and sales of three-way catalytic converters. It is deeply engaged in the field of new materials.
The company always keeps an eye on the industry frontier, actively learns from and draws on the advanced formulas and mature technologies of domestic and foreign counterparts. Through in-depth research and localization of mainstream formulas, it accurately adjusts the proportion of raw materials such as rare earths, precious metals and non-precious metals, so as to ensure that the coated carriers produced have stable catalytic activity and reliable performance.
The company's products cover a variety of specifications and models, and its products and technologies are applicable to automobiles, motorcycles, general-purpose engines, construction machinery, marine power, generator sets, agricultural machinery and other fields.
In the future, the company will continue to learn advanced industry experience, optimize production and services, and contribute to the realization of carbon peaking and carbon neutrality goals in China and around the world.
The silicon carbide DPF catalyst is a particulate filtration device that combines high mechanical strength, excellent thermal conductivity, and outstanding regeneration stability. It is one of the most balanced products in diesel aftertreatment systems in terms of structural and chemical performance. Its core substrate is made of high-purity silicon carbide (SiC), sintered at high temperatures to form a regular honeycomb channel structure. The inlet and outlet ends of each channel are alternately plugged, forcing the exhaust gas to pass through the porous walls, thereby efficiently capturing soot particles.
The thermal conductivity of silicon carbide is significantly higher than that of cordierite, allowing the DPF to rapidly and evenly distribute heat during regeneration, preventing local overheating that could lead to cracks or melting. The surface is typically coated with a catalytic active layer, which can incorporate different types of metal catalyst systems depending on the application—precious metal types (such as Pt, Pd) or non-precious metal types (such as CeO₂, Fe₂O₃, MnOx, etc.). This structure not only promotes the low-temperature reaction between NO₂ and soot during passive regeneration but also reduces the required regeneration temperature during active regeneration, effectively minimizing fuel consumption and thermal stress risks.
The filtration efficiency of the SiC DPF catalyst can stably remain above 95%, while maintaining a low rate of backpressure increase and strong resistance to ash accumulation. Its excellent mechanical stability allows it to withstand frequent regeneration cycles and high-temperature shocks, making it particularly suitable for heavy-duty vehicles, long-haul transportation, and off-road diesel equipment. Combined with advanced coating technologies and uniform airflow distribution design, the SiC DPF catalyst not only ensures long-term emission compliance but also extends system service life and reduces maintenance costs. It serves as one of the key core components in modern diesel aftertreatment systems.
