As critical components in high-stress lubrication systems, extreme pressure antiwear agents are specially engineered additives that form protective films on metal surfaces under severe operating conditions. Our advanced product line, including Active Sulfide Olefin ZT5540L and Sulfurized Isobutylene T321, represents cutting-edge sulfur-based chemistry designed to prevent welding, scuffing, and excessive wear in boundary lubrication regimes. These agents feature high sulfur content (38-46%) and are formulated as light yellow to yellow transparent liquids with excellent oil solubility. Through controlled chemical reactivity, they create sacrificial layers that protect metal components during extreme pressure events, making them indispensable for gear oils, metalworking fluids, and industrial lubricants operating under heavy loads and high temperatures.
Superior Extreme Pressure Protection: These additives function through controlled thermal decomposition, releasing active sulfur that reacts with metal surfaces to form iron sulfide layers under high-pressure conditions. This sacrificial film prevents metal-to-metal contact and welding, enabling equipment to withstand extreme pressures beyond the capability of conventional lubricants alone.
Enhanced Anti-Wear Performance: In addition to extreme pressure protection, these agents provide excellent anti-wear properties by forming durable surface films that reduce friction and wear in boundary lubrication conditions, particularly during startup, shutdown, and high-load operations where full fluid film lubrication cannot be maintained.
Optimized Reactivity Balance: Our products are engineered with carefully controlled reactivity levels - ZT5540L with high active sulfur content (35%) for maximum performance in severe metalworking applications, while T321 offers balanced reactivity with lower corrosivity for extended equipment protection in gear systems.
Exceptional Load-Carrying Capacity: The high sulfur content (up to 46% in T321) enables these additives to support extreme pressure conditions, significantly increasing the load-carrying capacity of lubricants and protecting critical components from failure under shock loading and high-stress operations.
Versatile Application Performance: These agents demonstrate excellent performance across various applications, from aggressive metal cutting operations to heavy-duty gear systems, providing reliable protection in diverse industrial environments including manufacturing, mining, and transportation.
Enhanced Compatibility and Solubility: Both ZT5540L and T321 exhibit outstanding solubility in mineral and synthetic base oils, ensuring homogeneous blending and stable performance in finished lubricant formulations while maintaining compatibility with other additive components.
Technical Superiority: T321 features additional benefits including low odor, light color, and reduced corrosivity to metals, making it suitable for higher-grade lubricants where these characteristics are essential for performance and user acceptance.
Metalworking Fluids: ZT5540L is particularly effective for demanding metal cutting and forming operations including turning, drilling, grinding, and tapping of carbon steel, cast iron, and stainless steel, providing exceptional performance in severe machining conditions.
Gear Oils: T321 is extensively used in middle and high-grade vehicle gear oils and industrial gear oils, protecting gear teeth from pitting, scuffing, and wear under heavy loads and shock conditions.
Industrial Lubricants: Both additives serve critical roles in various industrial applications including rock drill oils, compressor lubricants, and specialized greases where extreme pressure protection is required.
Formulation Synergy: These agents can be used individually or in combination with other extreme pressure additives such as sulfurized fats, chlorinated paraffins, and synthetic esters to achieve optimized performance profiles for specific application requirements.
Proven Performance in Severe Conditions: Our additives deliver reliable protection in the most demanding applications, with ZT5540L specifically engineered for harsh metalworking operations and T321 optimized for long-term gear protection in automotive and industrial systems.
Technical Expertise and Formulation Support: We provide comprehensive technical guidance to help formulators select the appropriate additive and dosage for specific applications, ensuring optimal performance while addressing compatibility considerations, particularly for non-ferrous metals.
Quality Assurance and Safety: Manufactured under strict quality control standards, our products come with complete safety documentation including MSDS, and are packaged and stored according to best practices to maintain product integrity and performance.
Cost-Effective Protection: The high efficiency of these additives enables formulators to achieve superior extreme pressure performance at economical treat rates, providing excellent value while extending equipment life and reducing maintenance costs.
