What is Alkenes C15-18 sulfurized PSAIL 3540?
Alkenes C15-18 sulfurized PSAIL 3540 (CAS No.: 91770-97-7) is a professional sulfur-based extreme pressure and anti-wear additive formulated with sulfurized C15-C18 alkenes as the core component. Featured with light color and low odor, this sulfurized alkene additive adopts high-activity sulfur formula to deliver stable and reliable lubrication performance. With low viscosity and excellent universal solubility, PSAIL 3540 shows favorable compatibility with various industrial base oils. The product maintains stable chemical activity at low temperatures, and its active sulfur content rises steadily with temperature increase, which enables controllable sulfur release performance under different working conditions. In addition, PSAIL 3540 can be compounded with other sulfur-containing and phosphorus-containing lubricant additives for customized formula design, serving as a versatile base additive for industrial lubrication and metalworking fluid formulations.
Features of Alkenes C15-18 sulfurized PSAIL 3540
Alkenes C15-18 sulfurized PSAIL 3540 possesses a set of stable and practical performance features suitable for industrial lubricant formulation and metal processing scenarios. Firstly, the product has a high effective sulfur content, which helps optimize formulation costs and provides cost-effective sulfur-based performance solutions for lubricant products. It adopts low-color and low-odor formula, which improves the appearance and usability of finished lubricants without causing strong odor pollution. Secondly, it delivers outstanding extreme pressure (EP) and anti-wear properties, effectively improving the friction resistance and load-bearing capacity of lubricating oils under heavy-duty conditions. The low-viscosity characteristic ensures good fluidity and dispersion in base oils, while its excellent compatibility allows stable blending with most conventional industrial base oils. Moreover, the product exhibits stable low-temperature reactivity and progressive active sulfur release as temperature increases, adapting to variable temperature working environments and meeting the performance requirements of continuous and intermittent machining operations.
Functions of Alkenes C15-18 sulfurized PSAIL 3540
As a high-activity sulfurized alkene extreme pressure anti-wear agent, Alkenes C15-18 sulfurized PSAIL 3540 undertakes core lubrication and protection functions in various lubricant and metalworking fluid systems. Its primary function is to provide reliable extreme pressure protection for mechanical contact surfaces under heavy-load and high-friction working conditions, reducing metal surface wear, friction loss and tool abrasion during machining processes. The gradually released active sulfur forms a stable protective film on metal surfaces, effectively avoiding scratches, galling and tool damage in high-load machining. It optimizes the overall lubricity of base oils and improves the operational stability of gear systems, hydraulic systems and mechanical moving parts. Meanwhile, the additive supports formula compounding with phosphorus and sulfur additives, helping balance the extreme pressure, anti-wear and oxidation resistance of finished lubricants, and extending the service life of lubricating media and mechanical equipment.
Applications of Alkenes C15-18 sulfurized PSAIL 3540
Alkenes C15-18 sulfurized PSAIL 3540 is widely applied in the formulation of industrial lubricants and metalworking fluids, covering multiple mechanical processing and equipment lubrication fields. It is commonly used for producing gear oils and anti-wear hydraulic oils, providing stable extreme pressure and anti-wear protection for industrial transmission and hydraulic equipment. The product is also applicable to the preparation of various lubricating greases to enhance the load-bearing and wear-resistant performance of grease products. In metalworking industries, it suits multiple machining processes including turning, drilling, grinding and tapping, serving as a key additive for heavy-duty metalworking oils and fluids. The recommended dosage ranges from 1.0% to 20.0% for metalworking oils and 1.0% to 5.0% for metalworking fluids. It is necessary to note that due to its high active sulfur content, this product is not suitable for machining non-ferrous metals such as copper and aluminum to avoid material corrosion. It can be directly added to lubricant formulations after compatibility pre-testing, and can be matched with RC 2540 and other related additives for compound use.
