SN500

Base oil SN500, also known as solvent neutral 500, is a type of mineral oil classified under Group I base oils according to the American Petroleum Institute (API) classification system. It is characterized by its moderate viscosity and high purity, making it suitable for a variety of lubricant and industrial applications. Here’s an overview of base oil SN500 and its primary uses:

Definition: Base oil SN500 is a light-colored mineral oil produced through solvent refining and hydroprocessing processes to remove impurities and improve its stability and performance characteristics. It typically exhibits a kinematic viscosity in the range of 60 to 74 centistokes (cSt) at 40°C and contains minimal levels of sulfur and other contaminants.

Uses:

Lubricant Manufacturing: Base oil SN500 serves as a base stock in the formulation of lubricants and functional fluids, including engine oils, hydraulic fluids, gear oils, and industrial lubricants. It provides the necessary viscosity and thermal stability to meet the performance requirements of lubricant products.

Industrial Lubrication: Base oil SN500 is used in various industrial applications for lubricating moving parts, reducing friction, and preventing wear and corrosion. It is commonly employed in hydraulic systems, compressors, pumps, turbines, and gearboxes across industries such as manufacturing, mining, construction, and transportation.

Metalworking Fluids: Base oil SN500 is utilized as a base fluid in the formulation of metalworking fluids, including cutting oils, coolants, and lubricants used in machining, milling, drilling, and metal forming operations. It helps to improve tool life, surface finish, and workpiece quality while providing cooling and chip removal.

Transformer Oils: Base oil SN500 is employed in the production of transformer oils, which are used to insulate and cool electrical transformers and equipment. It offers electrical insulation, heat transfer, and dielectric properties to protect transformers from overheating and electrical breakdown.

Rubber Processing: Base oil SN500 is used as a processing aid and extender oil in rubber compound formulations. It facilitates the dispersion of rubber additives, fillers, and chemicals during mixing, calendering, extrusion, and molding processes, enhancing the flow and properties of rubber compounds.

Adhesives and Sealants: Base oil SN500 is incorporated into adhesive, sealant, and caulk formulations as a plasticizer, lubricant, or carrier fluid. It improves workability, adhesion, and performance characteristics in construction, automotive, and industrial applications.

Paints and Coatings: Base oil SN500 is employed in the production of oil-based paints, varnishes, and coatings as a binder, solvent, or dispersant. It provides film-forming properties, gloss, and durability to paint formulations for architectural, automotive, marine, and industrial applications.

Ink Manufacturing: Base oil SN500 serves as a carrier fluid or vehicle in the formulation of printing inks, such as offset inks, gravure inks, and letterpress inks. It aids in pigment dispersion, viscosity control, and printability on various substrates.

Textile Lubrication: Base oil SN500 is utilized in the textile industry for lubricating yarns, fibers, and textile machinery during spinning, weaving, knitting, and finishing operations. It reduces friction, static electricity, and fiber breakage while improving productivity and product quality.

Fuel Oil Blending: Base oil SN500 can be blended with other petroleum products to adjust viscosity and improve fuel properties in fuel oil blending applications for marine, industrial, and power generation purposes.

Overall, base oil SN500 is a versatile base stock and functional fluid with applications in lubrication, metalworking, rubber processing, adhesive formulation, paint manufacturing, ink production, and various industrial processes. Its consistent quality, viscosity range, and thermal stability make it an essential component in lubricant and fluid formulations across diverse industries.
