Sodium petroleum sulfonate is an additive widely used in the field of lubricants. It has a variety of functions, including rust prevention, lubrication and cleaning, etc., providing efficient and environmentally friendly solutions for modern industrial and automotive fields.
- Anti-rust additives
Sodium petroleum sulfonate has excellent anti-rust properties. Adding sodium petroleum sulfonate to lubricating oil can effectively protect the metal surface from corrosion and prevent rust caused by oxidation and corrosion. This anti-rust function is particularly important for automobiles, machinery, electrical appliances and other equipment, because the metal parts in these equipment need to work under various environmental conditions for a long time and are susceptible to corrosion.
- Lubricant additives
Sodium petroleum sulfonate is also an excellent lubricant additive. It can form a uniform and stable lubricating film on the metal surface, reducing friction and wear, and improving the operating efficiency and service life of the equipment. At the same time, sodium petroleum sulfonate also has excellent low-temperature fluidity, which can maintain the performance of lubricating oil in low-temperature environments and is suitable for various extreme temperature environments.

- Cleaning additives
Sodium petroleum sulfonate also has cleaning properties. It can remove dirt and carbon deposits from metal surfaces, keep the engine clean, improve fuel economy and reduce emissions. At the same time, sodium petroleum sulfonate can effectively prevent the production of sludge and keep the lubricating oil clean and fluid.
Sodium petroleum sulfonate, as a multifunctional lubricant additive, performs well in rust prevention, lubrication and cleaning.
Applications of Sodium Petroleum Sulfonate:
- Engine Oils: Used in automotive, marine, and industrial engine oils to improve cleanliness, wear protection, and corrosion resistance.
- Metalworking Fluids: Employed in cutting fluids, coolants, and hydraulic fluids to enhance lubrication, cooling, and corrosion protection.
- Industrial Lubricants: Utilized in gear oils, hydraulic fluids, and circulating oils to improve EP properties, wear protection, and equipment reliability.
