When a thickening agent is added to a liquid lubricant, grease is created as a semi-solid substance. It includes an additive, a thickener, and an oil chemical mixture.
The basic oil and additives employed in formulations play a large role in determining the behaviour of grease. To increase the working efficiency of the grease, additives are utilised to enhance desired characteristics, inhibit undesirable properties, or introduce new features.
The Global Water-resistant greases market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
For the North American market, DuPont unveiled their new line of MOLYKOTE Polyalphaolefin Greases, including MOLYKOTE G-1033 Grease, MOLYKOTE G-1041 Grease, and MOLYKOTE G-1057 Grease.
To optimise design freedom in both the consumer and industrial industries, the three novel greases are designed for a variety of plastic-to-plastic and plastic-to-metal interfaces.
In order to extend the service life of bearings working in difficult and demanding work situations, Schaeffler India has introduced XTRA3, a new high-performance multi-purpose premium grease.
The mineral oil-based grease with lithium-soap thickening has been rigorously tested at high temperatures at the Schaeffler laboratory in Germany and is FE8 & FE9 certified, making it incredibly reliable for demanding applications.
LNEP 2IN, a high-load, extreme-pressure bearing grease, was introduced by SKF. This grease has been specifically designed to lengthen the useful life of bearings operating in difficult conditions and to uphold SKF’s commitment to global quality and dependability throughout all geographies.
Good mechanical stability, high water resistance, and corrosion protection are all provided by LNEP 2IN.
It is challenging to succinctly describe a grease’s overall water resistance because water influences numerous properties. As a result, numerous relevant properties and tests for evaluating them have been found. Demulsibility, water saturation point, water absorption potential, water absorption facility, and water penetration depth tests are among the new recommended tests.
Existing grease tests should also be used to compare samples that have been contaminated with water to those that have not. These tests might be useful for describing how a grease performs differently when it is contaminated with other contaminants or is degraded in another way.Users do not have access to sufficient information regarding the capabilities of greases in moist environments.
The fundamental mechanics of the interaction between grease and water, particularly the transport of water within grease, would likely yield useful information regarding how water affects lubrication performance. Understanding how water affects the overall degradation of grease is also desirable.
An effective model for the prediction of grease life in wet environments could be developed by examining how water affects grease’s mechanical and chemical degradation. In contrast to the tests that are currently in use, researchers who are looking into how water affects mechanical degradation should keep in mind that, in order to emulsify water, some amount of mechanical shear is required, likely resulting in significant structural damage.
When looking at a grease’s water resistance, there are a lot of different properties to consider, and there is no one definition that says which grease is best for all applications. In point of fact, even if a grease is designed to perform well in some tests, it is likely to perform poorly in others.
So, it’s important to know how a device is lubricated so that the user can look for a grease with the right balance of properties and the most important water-resistant features. To put it succinctly, a grease that is water-resistant is one that possesses the optimal combination of properties for a particular wet environment.. While industry standards attempt to evaluate a grease’s water resistance, research indicates that a more thorough understanding of water resistance is needed to properly match a grease to an application.
