Founded in July 2024,As China SCRF (DPF Coated with Cu-Fe Base) Catalyst Suppliers and Wholesale SCRF (DPF Coated with Cu-Fe Base) 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.
SCRF catalysts integrate SCR functionality directly onto a diesel particulate filter (DPF), combining NOx reduction and particulate filtration into a single unit. These catalysts typically employ both copper and iron as active components on a ceramic or metallic DPF substrate.
The Cu-Fe SCR coating leverages TiO₂ as the primary support, with copper providing excellent low-temperature activity and iron enhancing high-temperature performance. This dual-metal design allows the SCRF to maintain high NOx conversion across a broad temperature range while simultaneously supporting passive or active DPF regeneration. The coated DPF ensures uniform exhaust flow, minimizes NH₃ slip, and maintains structural integrity under thermal cycling, making it ideal for modern diesel engines with compact after-treatment layouts.
