Description
Sinopec Moly-Lithium Heavy Duty Grease is a high extreme pressure lubricating grease, formulated with lithium soap thickener and high-quality mineral base oil, combined with selected additives. It is specially enhanced with solid lubricating additive Molybdenum disulfide (MoS2 or ‘moly’). This additive has extreme pressure properties, enhancing the grease’s anti-wear capabilities. Available in NLGI grades 1, 2, and 3.
Applications:
Sinopec Moly-Lithium Heavy Duty Grease is suitable for use in:
- Bearings and gears of heavy-duty equipment operating under vibrating/oscillating conditions, such as those used in the steel and mining industries, where extreme pressure/anti-wear grease is required.
- Applications where the temperature range is from –20°C to +120°C.
Features and Benefits:
- Excellent Anti-Wear and Extreme Pressure Properties: Protect bearings from wear under heavy and shock load conditions, extending equipment life.
- Solid Lubricating Additive with Molybdenum Disulfide (MoS2): Enhances load-carrying capacity and protects metal surfaces from wear in conditions where vibratory shock loads can expel grease from metal surfaces.
- Lithium Soap Thickener: Ensures good mechanical stability, so the grease structure does not soften or break down in service.
- Good Water Resistance Properties: Ensure that the grease is not easily washed out of bearings or gear surfaces, providing optimal protection.
- Excellent Water Resistance: Ensures the grease remains in place and is not washed or sprayed off in wet conditions, reducing grease wastage.
- Good Adhesiveness: Ensures the grease sticks to metal surfaces, preventing dirt and abrasive materials from entering, thereby extending lubrication intervals.
- Good Rust and Corrosion Protection: Extends component life and re-lubrication intervals.
- Available in NLGI Grades 1, 2, and 3: To meet the requirements of specific applications.
