Description
Sinopec Extreme Pressure Lithium Complex Grease is an extreme pressure grease, formulated with a lithium complex soap thickener and high-quality mineral base oil. It contains rust and oxidation inhibitors, EP additives, and antiwear additives to ensure excellent performance and long life, even under severe service conditions such as high temperatures, shock loading, and water contamination. Available in NLGI grades 1, 2, and 3.
Applications:
Sinopec Extreme Pressure Lithium Complex Grease is suitable for use in:
- Bearings operating under high loads or shock loads and at high temperatures, for example in the metallurgical industry, where an extreme pressure grease is required.
- Other high-temperature grease applications, for example in the dyeing and printing industries.
- Oil pump bearings of high-capacity cars, running at high temperatures.
- Applications where the temperature range is from –20°C to +160°C.
Features and Benefits:
- Excellent Extreme Pressure and Antiwear Properties: Protects heavily loaded or shock-loaded bearings from wear, extending equipment life.
- Lithium Complex Soap Thickener: Ensures a high dropping point, which means that the grease can be used at higher temperatures in severe service applications (–20°C to +160°C), and also confers excellent mechanical stability so that the grease structure does not break down in service.
- High-Quality Base Oil: Ensures a good oil film thickness is maintained, even in high-temperature applications, protecting components against wear.
- Excellent Water Resistance: Means that the grease stays in place and is not washed or sprayed off in wet conditions, reducing the need for frequent re-application.
- Protection Against Rust and Corrosion: Ensures long component life and extends maintenance intervals.
- Thermal and Oxidation Stability: Ensures longer grease life under high-temperature conditions, providing optimum lubrication, extending equipment life, and reducing maintenance requirements.
- Available in NLGI Grades 1, 2, and 3: Meets the requirements of specific applications.
