Thermal Stability Drop Point: The temperature at which grease transitions from a semi-solid to a liquid state. A high drop point indicates good thermal stability and suitability for high-temperature applications. Oxidation Resistance: Greases should resist oxidation to prevent thickening and formation of acidic by-products, which can lead to corrosion and reduced lubrication effectiveness. 4. Water Resistance Water Washout: The ability of grease to resist being washed away by water, which is critical for applications exposed to moisture, such as in marine or outdoor environments. Water Absorption: Greases should have low water absorption to prevent emulsification and maintain lubricating properties. 5. Mechanical Stability Shear Stability: The ability of grease to maintain its consistency under mechanical stress and shear forces. Greases with good shear stability do not break down easily during operation. Worked Stability: The consistency change after the grease has been mechanically worked, which indicates its durability in real-world applications. 6.

Corrosion and Rust Protection Corrosion Inhibitors: Additives that protect metal surfaces from rust and corrosion, especially important in harsh or humid environments. Salt Spray Test: Evaluates the grease's ability to protect against corrosion when exposed to a saline environment. 8. Adhesion and Tackiness Stickiness: Greases should adhere well to surfaces and remain in place, even under vibration and centrifugal forces. This ensures continuous lubrication and protection. Cohesion: The internal bonding strength of the grease, which prevents it from breaking apart under stress. 9. Compatibility Material Compatibility: Greases should not react negatively with metals, plastics, or elastomers used in the machinery. Compatibility ensures that the grease does not cause swelling, degradation, or other damage. Grease Compatibility: The ability to mix with other greases without adverse chemical reactions or performance degradation, which is important during maintenance and re-lubrication. 10. Environmental and Health Safety Biodegradability: Environmentally friendly greases that break down naturally without causing harm to ecosystems.
