Introduction
High Temperature Greases are a unique kind of lubricant that can bear elevated temperatures without losing its original properties. The major difference between standard grease and high temperature grease is that standard grease can break down under intense heat causing extreme friction and equipment wear whereas high temperature grease maintains its consistency and protective properties even in difficult conditions. Thus, high temperature grease is considered ideal for various industries such as manufacturing, automotive and construction.
Benefits of High Temperature Grease
Following are the key benefits of high temperature grease that makes it useful and ideal for industrial use:
- Heat Resistant: This grease can bear the temperatures up to 250°C and higher without breaking down and ensure a stability in the lubrication process.
- Better Equipment Life: High temperature grease can extend the lifespan of critical and essential equipment parts by reducing friction and preventing wear during the lubricating process.
- Safety: This grease also prevents overheating and abrupt breakdowns and ensures safety of the equipment.
- Reduction in Downtime: As high temperature grease reduces the chances of equipment breakdown, it boosts the overall productivity of those equipment.
- Lubricants: Lubricants with special components are used to maintain the stability of grease even in high temperatures. These lubricants play a key role in the prevention of equipment breakdown and increasing the efficiency of the machines.
- Heat-Resistant: High temperature greases are composed in a way that they can handle high heat and temperatures and give ideal performance during the operations.
- Lubricants for Machineries: High Temperature grease is made up of lubricants that can help in maintaining the proficiency and life span of the machines. Those lubricants reduce the friction between the parts and maintain the efficiency of the equipment.
- Heavy-Duty Grease: This grease also consists of properties that can bear heavy load and give the best outcome under stressful conditions.
Types of High Temperature Grease
Some of the common types of high temperature grease that are often used in industrial sector are as follows:
- Lithium Complex Grease: Lithium complex grease is considered ideal for heavy-duty applications as it is highly resistant to water, temperature and oxidation.
- Polyurea Grease: Polyurea grease is widely used in electric motors due to its excellent oxidation properties. This grease can give best performance during high-speed and high-temperatures.
- Calcium Sulfonate Grease: Calcium Sulfonate Grease has properties such as thermal stability and is resistant to corrosion which makes it a perfect choice for marine, off road and heavy applications.
- PTFE Grease: PTFE grease is commonly known as Teflon which provides brilliant lubrication by reducing the friction. It is chemical, moisture and high temperature resistant and is used for carrying out operations smoothly.
- Molybdenum or Graphite Based Grease: This grease is a mixture of molybdenum disulfide and graphite which makes it ideal for operations requiring high temperatures and extreme pressures. This grease is mixed with anti-seize paste which also makes it suitable for wear protection.
- Non Melting Grease: Non melting grease is used in ovens, kilns and machines with high temperatures as it maintains its structure even under extreme heat. They are also used with anti-seize paste which offers thermal stability to the performance of the machinery.
- Synthetic Grease: Synthetic Grease is designed to resist oxidation, bear high temperatures and deal with harsh environments. They are also combined with anti-seize paste and deliver precision in performance and long-term lubrication intervals according to the need of applications.
Factors To Be Considered While Choosing High Temperature Grease
It becomes very important to choose the correct type of high temperature grease that can be accurate and beneficial for the machinery. Below stated are few factors to be kept in mind while choosing the correct high temperature grease:
- Range of Temperature: It should be ensured that the chosen grease is able to bear the highest temperatures that the machinery can come across.
- Load Requirements: It is essential to choose grease that is made up of extreme pressure additives (EP) for the high-load machinery.
- Resistant to Water: It is important to know whether the machine operates in wet conditions or not. If the machine demands wet conditions as well, it is better to select a water-resistant grease that can provide a better outcome
- Frequency of Relubrication: Another important thing to note is whether the equipment necessitates minimal access for relubrication. If yes, it is advisable to choose a long-lasting grease for better outcome. Usually, relubrication of grease depends on the machinery and type of grease.
How High Temperature Grease Works
It is important to know how high temperature grease works before selecting the right type of grease for your equipment. High temperature grease is a mixture of high viscosity base oil and unique kind of thickeners such as lithium complex or calcium sulfonate. This unique composition helps the grease to be stable during harsh environments. This unique mixture also includes performance additives anti wear agents and corrosion inhibitors that help the machinery to fight against wear and environmental factors. The most important feature of high temperature grease is its consistency which leads to equal distribution of heat across all the parts, prevents hotspots and runs the operation smoothly.
