sinopec-7025-high-temperature-synthetic-grease

The Aviation Grease Series (Models 7017-1B, 7023B, 7025, 7501, and 7008) represents a full range of high-performance lubricants designed to meet the strict demands of the aviation industry, precision machinery, electromechanical equipment, and special high-/low-temperature environments. Manufactured with advanced complex agents, premium base oils, and carefully selected additive packages, these greases deliver long-lasting lubrication, oxidation stability, and strong protection under extreme working conditions.

Among these products, Aviation Grease 7025 is one of the most widely used high-temperature aviation greases and is the highlighted model in this product page. With a drop point of 260°C and an operating temperature range of –40°C to 200°C, it ensures stable lubrication in demanding thermal environments such as high-temperature motors, kiln cart bearings, precision rolling elements, and heavy-load sliding systems. Its light brown to brown uniform appearance reflects its refined formulation and strong resistance to mechanical shear, providing a long service period even under continuous high-speed operation.

The Aviation Grease Series provides comprehensive coverage for a diverse set of applications:

• 7017-1B High and Low Temperature Grease is specially engineered for systems exposed to both severe cold and high heat. Operating between –60°C and 180°C, it is suitable for aviation motors, electronic instruments, and precision bearings that demand consistent performance across temperature extremes. The worked penetration of 265–295 (0.1mm) ensures reliable consistency and long-term structural stability.

• 7023B Low Temperature Aviation Grease performs exceptionally in freezing environments, with an operating range of –55°C to 120°C. This grease is especially useful in aircraft machinery, aerospace bearings, and cold-region equipment requiring reliable lubrication at subzero temperatures.

• 7501 High Vacuum Silicone Grease serves specialized scientific and industrial fields such as vacuum coating machines, sealed glass pistons, and laboratory ground-joint assemblies. With an operating range from –40°C to 200°C, it offers superb sealing capacity, chemical stability, moisture resistance, and low vapor pressure—making it essential for high-vacuum systems.

• 7008 General Aviation Grease, a versatile and widely adopted model, features a drop point of 250°C and an operating temperature range of –50°C to 120°C. It is suitable for bearings and gears in motors, electromechanical equipment, high-speed micro-motors, and precision instruments. With balanced oxidation stability, mechanical stability, and noise-reduction performance, it is often used as an all-purpose aviation and industrial lubricant.

The featured product Aviation Grease 7025 is formulated using a complex soap thickener system, enhanced with structural modifiers and antioxidant agents. Its key functions include:

• Excellent high-temperature and low-temperature performance, ensuring fluidity in cold environments and stability at high heat.

• Strong oxidation resistance, reducing the formation of sludge and deposits.

• Outstanding mechanical stability, preventing softening or leakage during long-term high-load conditions.

• Good colloidal stability, preventing oil separation.

• High-speed and noise-reduction capabilities, making it suitable for precision aviation bearings.
