Grease is an essential part of our machinery to keep it functioning under intense heat. High temperature grease is extremely crucial to keep the automotive and aerospace applications industry running.
These greases are responsible for ensuring the optimal performance of machinery by keeping it well-lubricated under extreme heat conditions. However, the industry is moving towards a more sustainable future, where efficiency and durability are valued.
Therefore, the time has come for high temperature grease to evolve as well. The industry is looking for more innovative and eco-friendly greases that can fulfil sustainable goals. So, in this article, let us explore those greener alternatives and see how the overall industry is shifting towards them.
What is High Temperature Grease Used in the Industry?
At its core, grease is a lubricant agent that is made up of 70-90% base oil, which is often mineral or synthetic oil. Furthermore, it has a thickening material, which is made up of metallic soaps like lithium or calcium. Lastly, the grease also contains additives that enhance properties like oxidation resistance, anti-wear, and friction reduction.
On the other hand, high temperature grease is designed specially to tolerate extreme thermal conditions. Such ability enables the grease to provide lubrication, reducing friction and preventing wear in machinery. Moreover, the compositions mentioned earlier also assist in resisting heat and increase the performance of the machines. So, what are the advantages that such greases provide?
One of the prime features of high temp grease is providing thermal stability to the machinery parts under intense heat. The grease can keep the parts lubricated without breaking down under severe heat.
On the other hand, these greases also have a high oxidation resistance, which means they can prevent degradation and ensure longevity. They also have higher load-bearing capacity, which offers protection under heavy mechanical stress as well as a low evaporative rate.
How Innovation is Taking Over High Temperature Grease?
Over the years, the grease has seen a high amount of innovation take place. For example, smart grease is becoming a reality. Integration of IoT sensors allows real-time monitoring of grease conditions.
These sensors are capable of analysing material states like viscosity, degradation rates, and temperature fluctuations. Such pieces of information help to optimize maintenance schedules properly. But there are even more innovations.
Nano-Technology in Grease: Nanoparticles such as graphene and tungsten disulfide can enhance grease performance at a molecular level. These materials are responsible for improved thermal conductivity, wear resistance, and excellent stability under extreme heat.
Synthetic & Bio-Based Blends: This is a new hybrid solution that combines synthetic oils with bio-based material. This hybrid of two materials achieves the effect of maintaining better viscosity while reducing environmental impact. For bio-based material, esters, biodegradable oils, and plant-based lubricants are used that enhance sustainability as well.
Adding High-Performance Additives: Various advanced additives are added to the grease to improve its high-temperature endurance and minimise wear. Materials like molybdenum disulfide and ceramic compounds are responsible for many such improvements.
Self-Healing Grease Technology: With modern technology, certain greases are now being developed to self-heal. In particular, high temperature grease can now self-repair or regenerate over time. This is possible thanks to the microcapsule technology, which helps the grease respond to the degeneration and restore its lost lubrication in the process.
What are the Eco-Friendly Greases in the Industry?
As mentioned earlier, the industry is gradually shifting towards sustainable practices, and high temperature grease is no different. Biodegradable grease is a good example to start with, as after its use, the grease can naturally break down without producing any toxic byproducts.
These greases are typically made up of plant-based oil and other renewable materials:
Non-Toxic Alternatives: Many companies prefer greases that avoid the use of toxic chemicals in their composition. Thus, the industry has come up with non-toxic, solvent-free compositions in greases. Therefore, when the grease breaks down, no toxic chemicals are released into the environment.
Low-Carbon Footprint Manufacturing: Some grease is also being produced that reduces their carbon emission. These high temperature greases are highly efficient and help factories or other machinery to minimise consumption and waste of energy.
Recyclable & Reusable Greases: There is also an effort to make greases renewable by making the core lubricant solution recyclable. By making grease reusable, a whole lot of material is saved, as well as the energy that goes into making new grease. Therefore, some greases now include recycling-compatible additives for easier separation and reapplication.
Polyalkylene Glycols (PAGs): These types of grease are derived from the reaction of ethylene and propylene oxides with alcohol or water. One of the best qualities of this grease is its high viscosity index, low pour point and exceptional lubrication for metal-to-metal applications. Though the material is more expensive than normal grease, it offers excellent cleanliness and stability.
What are the Real Benefits of Using Eco-Friendly High Temperature Grease?
We know that reality is many times far removed from the ideal. However, it is important to know that there are actual benefits of switching to eco-friendly greases. We know that there is always the risk of accidental spills or leaks that can damage the environment. Thus, apart from the usual benefits like reduced soil, water and air pollution, there are many other benefits as well.
For instance, environmental damage can get a company in trouble with the government they are operating under. Any company will be at much ease if it follows the stringent environmental regulations and permits earlier. But one of the biggest gains with eco-friendly high temperature grease is reduced energy cost, as these greases are more efficient as well as renewable.
Conclusion
It is now pretty evident that the industry is moving towards a sustainable future, and modern innovations are helping to attain that goal. The path towards this goal is pretty simple: make high temperature grease more efficient and reusable.
If the current trajectory continues to go like this, we will see the next generation of high-temperature greases, be smarter, greener, and more adaptive. With all the new technology, it can be said with confidence that this envisioned future is not too far away.
