3. General Application Markets

- Lubricant Additives: Primary use as multi-functional friction modifier, antiwear (AW), extreme pressure (EP), and antioxidant additive

- Engine Oils: Automotive passenger car, heavy-duty diesel, and motorcycle engine oils for fuel economy and wear protection

- Industrial Lubricants: Gear oils, hydraulic oils, compressor oils, turbine oils, and way lubricants

- Greases: Lithium, calcium, polyurea, and complex greases for high-temperature, heavy-load bearings

- Metalworking Fluids: Cutting oils, rolling fluids, and drawing fluids for heavy machining

- Chemical Industry: Catalyst for alkylation, isomerization, and oxidation reactions; polymer stabilizer

- Agriculture: Plant growth regulator and pesticide additive (minor use)

4. Lubricant Additive Analysis

4.1 Functional Mechanism

- Friction Reduction: Under frictional heat and pressure, decomposes to form nanoscale MoS₂ films on metal surfaces, lowering friction coefficient by 30–50% an
- Antiwear & Extreme Pressure: Forms durable sulfur-molybdenum tribofilms that prevent metal-to-metal contact, scuffing, and seizure under heavy loads

- Antioxidation: Inhibits oil oxidation by neutralizing peroxides and free radicals, extending oil drain intervals and reducing sludge/varnish

- Synergism: Works with ZDDP, ashless dithiocarbamates, phenols, and amines to boost overall performance

4.2 Key Performance Advantages

- Phosphorus-Free: Complies with low-P/zero-P regulations for modern engines and emission systems (DPF, catalysts)

- Multi-Functionality: Combines friction reduction, AW/EP, and antioxidant in one additive, simplifying formulations

- High-Temperature Performance: Stable in severe operating conditions (150–200°C) common in gears and bearings

- Low Corrosion: Minimizes attack on yellow metals (copper, brass) vs. sulfur-phosphorus additives

- Fuel Economy: Significant friction reduction improves fuel efficiency in automotive and industrial engines

Product features:

Ultra low ash, low phosphorus, low sulfur, and post-treatment protection

Low conductivity, insulation, copper aluminum corrosion resistance, low friction, high speed stability

Sulfur free, ash free, hydrogen embrittlement resistant, high temperature resistant.
