High Temperature Grease

High Temperature Grease is a grease specially designed to provide effective lubrication and protection in high temperature environments. It is usually composed of a variety of additives such as base oil, thickener, antioxidant, defoamer, etc. to meet the lubrication needs under extreme working conditions such as high temperature, high pressure, and high speed.

Features

Excellent high temperature resistance: High Temperature Lubricating Oil can maintain its lubrication performance in high temperature environments without deterioration, solidification, or excessive evaporation. This feature enables it to provide continuous lubrication protection for equipment under extreme high temperature conditions.

Good thermal stability: High temperature lubricating oil has good thermal stability and can maintain stable lubrication performance at high temperatures, thereby ensuring long-term stable operation of the equipment.

Strong antioxidant performance: Due to the addition of antioxidants, high temperature lubricating oil can effectively resist oxidation, extend service life, and reduce the maintenance cost of the lubrication system.

Good shear resistance: In high temperature, high pressure, and high shear working environments, high temperature lubricating oil can maintain its lubrication effect and prevent equipment from being damaged due to poor lubrication.

Low volatility: High temperature lubricating oil evaporates less at high temperatures, which can reduce the loss of lubricating oil and improve lubrication efficiency.

Good compatibility: High-temperature lubricants usually have good compatibility and are compatible with a variety of materials (such as metals, rubbers, plastics, etc.) to avoid chemical reactions or corrosion.

Application areas

Industrial equipment: In high-temperature and high-pressure industrial environments, high-temperature lubricants can provide effective lubrication protection for various industrial equipment. For example, in industrial equipment such as machine tool spindles, fans, high-speed motors, and engine bearings, the high-temperature environment generated by high-speed rotation and friction has high requirements for lubricants, and high-temperature lubricants can meet these specific requirements and ensure the normal operation of the equipment.

Automobile manufacturing: In the field of automobile manufacturing, high-temperature lubricants are widely used for the lubrication of key components such as engines, gearboxes, and transmission systems. These components operate in high-temperature, high-pressure, and high-speed working environments, and require high-quality lubricants to provide lubrication and protection.

Aerospace: In the field of aerospace, high-temperature lubricants also play an important role. Since aerospace equipment needs to operate in an extremely high-temperature and high-pressure environment, lubricants with excellent high-temperature resistance and high thermal stability are required to ensure the normal operation and safety of the equipment.

Electronics industry: In the electronics industry, high-temperature lubricants are used for lubrication and heat conduction between radiators and electronic components. For example, applying high-temperature lubricating oil on heating components such as CPU and GPU of computers and servers can improve heat dissipation efficiency, reduce equipment temperature, and thus extend the service life of the equipment.

Other fields: In addition, high-temperature lubricating oil is also widely used in ships, railways, metallurgy, chemical industry and other fields to provide lubrication and protection for equipment in various high-temperature environments.
