What is a Non-Melt Grease/ Non-Drip Grease | Important Facts of Non-Melt Grease


Non-melt Grease popularly known as Non-drip Grease is a high–performance lubricant that helps in reducing maintenance downtime and increased re – lubrication interval. It performs satisfactorily at elevated temperatures and is generally oxidation resistant.

Let’s understand more in details about the Non-melt Grease and understand how it acquired its property

What do you think Non-melt Grease is and how it acquired its property?

Non-melt Grease is a lubricating grease with a none drop point. The grease acquires this property from its thickener. Some thickeners are non – melting and withstand temp that is hotter than what conventional greases can handle. Inorganic thickeners have no drop pint and perform well at an elevated temperature range. Popular inorganic thickeners are Silica, Organoclay, Carbon black, etc.

Pros of using Non-melt Grease

  • High-performance Lubricant
  • Performs well at elevated temperatures subject to the suitability of base oil
  • Good oxidation stability at high temperatures
  • Performs well in adverse conditions

Challenges faced by Non-melt Grease are the same as that of other lubricating greases i.e. Caking of grease, Oil running out of grease, Compatibility issues, Pumpability, etc. However, caking of grease at high temperature remains the most common cause of concern while using a Non-melt Grease with a base oil that is not suitable for such high temperatures.

Some interesting facts of Non-melt Grease

– Non-melt Greases are suitable for the high-temperature application, but one should keep in mind that the thickener used is non-melt but additives and base oil have an upper operational temperature limit.

– Non-melt Grease also has the potential for thickening at lower temperatures. During the selection of lubricant, one should not only consider the heat to which grease would be subjected but also the overall temperature range.

– It is also important to check the grease compatibility. One must know which grease is applied before and if it is the correct one. Cross-contamination is a major problem in grease.

– While considering a Non-melt Grease for higher temperatures one should consider other parameters like the base oil being used otherwise oil burning can occur which can result in thickener residue.

– Over greasing is always a common challenge with greasing, especially for Non-melt Grease one considers the considerate and calculated quantity of grease for filling and relubrication.
