Learn More About Technical Data Sheet (TDS) of Grease
A Grease Technical Data Sheet (TDS) is a guiding and reference technical document that provides detailed product information include grease typical characteristic data, formulation, and performance data to help users choose and use the right lubricant for specific applications. It is an important document to display chemical greases and lubricant.
Today let us learn more about the general indicators of this document, Here we explain the key parameters used to characterize and evaluate.
grease products:
Grease Products:
① Appearance
This refers to the visual characteristics of the grease, including:
1.Color ( clear/translucent to various colors)
2.Texture (smooth, fibrous, or grainy)
3.Consistency (soft, firm, or hard)
4.Homogeneity (uniform or containing lumps/separation)
5.Lubricant color or texture is generally affected by additives
② NLGI Grade (National Lubricating Grease Institute)
③ Base Oil
④ Thickener
⑤ Dropping Point
⑤ Dropping Point
Measures the tendency of base oil to separate from the thickener:
● Usually measured at elevated temperatures over time
● Expressed as percentage of oil separated
● Lower rates indicate better storage stability
● Important for long-term storage and equipment protection
⑦ Evaporation Rate
The rate at which the grease loses volatile components:
● Measured at high temperatures over specific time periods
● Expressed as weight percentage loss
● Lower evaporation rates indicate better high-temperature stability
● Critical for applications with heat exposure
Conclusion
These parameters work together to define a grease's suitability for specific applications, operating conditions, and performance requirements. Understanding them helps in proper grease selection and application.
