Sinopec Extreme Pressure Lithium Base Grease
Sinopec Extreme Pressure Lithium Grease NLGI 1 is a high-performance lubricating grease specifically designed for heavy-duty applications. It is formulated with a lithium soap thickener and high-quality base oils. This grease contains extreme pressure (EP) additives, rust inhibitors, oxidation inhibitors, and anti-wear additives, providing excellent performance and long service life, even under harsh conditions such as high temperatures, heavy loads, and water contamination.
Applications: Sinopec Extreme Pressure Lithium Base Grease is suitable for use in:
- Bearings and gears of medium to heavily loaded mechanical equipment, where an extreme pressure/antiwear grease is required.
- Applications where the temperature range is from –20°C to 120°C.
Features and Benefits:
- Excellent Extreme Pressure and Antiwear Properties: Protects heavily loaded or shock-loaded bearings from wear, extending equipment life.
- Lithium Soap Thickener: Ensures good mechanical stability, so the grease structure does not soften or break down in service.
- High-Quality Base Oil: Ensures a good oil film thickness is maintained, even in high-temperature applications, protecting components from wear.
- 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.
- Strong Adhesion to Metal Surfaces: Seals out dirt and abrasive materials, ensuring longer lubricating intervals.
- Available in NLGI Grades 00, 0, 1, 2, and 3: Meets the requirements of specific applications.
