7023B Low-Temperature Grease
High-Performance Lubrication for Extreme Cold and Wide-Temperature Applications
SINOPEC 7023B Low-Temperature Grease is a high-quality specialty grease formulated with a complex thickening agent and selected base oils, enhanced by advanced additives for anti-oxidation, corrosion protection, mechanical stability, and long-term lubrication performance. The product is designed to deliver reliable lubrication under both extremely low temperatures and elevated operating conditions, making it suitable for aviation, automotive, and industrial applications.
7023B grease demonstrates excellent low-temperature start-up characteristics, strong adhesion, and stable grease structure, ensuring consistent lubrication without hardening, oil separation, or leakage. It complies with Q/SH3031 0124 technical specifications and is produced under strict quality control systems of SINOPEC (Great Wall Lubricants).
Excellent Low- and High-Temperature Performance
One of the most important advantages of SINOPEC 7023B is its wide operating temperature range, covering both extreme cold and moderate high-temperature conditions. The grease remains soft and workable at low temperatures, with a similar viscosity of 876 Pa·s at –50°C, ensuring smooth motion, reduced friction, and reliable protection during cold starts.
At higher temperatures, its high drop point (>250°C) and strong oxidation resistance allow the grease to maintain structural integrity and lubrication performance, even under prolonged thermal stress. This balanced performance makes 7023B suitable for applications requiring temperature adaptability across different climates.
Superior Protection and Lubricity
7023B Low-Temperature Grease provides excellent rust prevention and corrosion resistance, effectively protecting steel and copper alloy components from moisture, oxidation, and environmental attack. The grease passes copper corrosion and protective performance tests, confirming its suitability for long-term equipment protection.
Its good lubricity and load-carrying capability help reduce wear on bearings, sliding parts, and mechanical assemblies, extending service life and reducing maintenance frequency. This is especially valuable in automotive and precision mechanical systems where smooth movement and durability are essential.
High Stability, Adhesion, and Storage Performance
The product features outstanding colloidal stability and mechanical stability, preventing oil separation or excessive softening under mechanical shear or vibration. Its strong adhesion ensures that the grease remains firmly attached to lubricated surfaces, minimizing grease loss and ensuring continuous protection.
In addition, SINOPEC 7023B offers excellent storage stability, maintaining consistent quality and performance during long storage periods when handled and stored correctly.
Application Areas
SINOPEC 7023B Low-Temperature Grease is available in A-grade and B-grade, covering both aviation and civil mechanical applications:
-
A-grade:
Designed for the lubrication and protection of aircraft gun systems, landing gear retraction mechanisms, and aircraft control systems
Operating temperature range: –60°C to +120°C -
B-grade:
Designed for automotive and civil machinery, such as automotive window regulators, precision mechanisms, and low-temperature industrial equipment
Operating temperature range: –50°C to +140°C
The product has also been successfully applied in air separation equipment and export automotive components, effectively solving low-temperature hardening and poor lubrication issues found in conventional lithium greases.
Handling and Usage Recommendations
-
Thoroughly clean lubricated parts before application.
-
Do not mix with other greases to avoid incompatibility and performance loss.
-
Prevent dust, moisture, and contaminants from entering during storage and use.
