Viscosity: 10.2–10.75 mm²/s at 50°C; 842–826.2 mm²/s at -50°C, demonstrating superior low-temperature fluidity.

2. Chemical Stability & Durability

Antioxidant additives: Contains 264-type antioxidants to delay oxidation and extend service life.
Corrosion resistance: Copper strip corrosion ≤1b (at 70°C), effectively protecting metal components.
Purity control: Moisture content ≤36 mg/kg; no mechanical impurities, ensuring system cleanliness.

3. Physical Properties

Flash point: ≥110°C (open cup), ensuring high safety.
Density: ≤840 kg/m³ at 20°C, aligning with lightweight aviation system requirements.

4. Specialized Performance Tests

Air oxidation stability (SH/T0196): Minimal acid value and viscosity changes, low sediment formation.
Shear stability (SH/T0505): High resistance to viscosity loss under shear stress.

III. Application Scenarios

1. Aviation Sector

Military: Used by PLA Air Force, AVIC, etc., in fighter jets, helicopter systems, landing gear, and speed brakes.
Civil: Suitable for general aviation and ground equipment in polar regions.

2. Specialized Environments

Arctic machinery: Polar expedition equipment, port machinery in cold climates.
High-pressure systems: Hydraulic switches, dump truck transmissions.

IV. Comparison with Kunlun 10 Aviation Hydraulic Oil

Parameter	Teli 10 (Sky)	Kunlun 10 (Sky)	Conclusion
Key specs	Pour point: -75°C, 50°C viscosity: 10.75 mm²/s	Pour point: -73°C, 50°C viscosity: 11.4 mm²/s	Teli excels in low-temperature performance
Brand background	Shenyang Teli (private, ex-Sinopec JV)	CNPC Kunlun (state-owned)	Kunlun has higher brand trust; Teli offers cost efficiency
Applications	Dual military-civilian use, civilian focus	Military preferred (state-owned policy)	Kunlun for military; Teli for civilian
Cost & supply	Lower procurement cost, flexible supply	Higher price, stable state-owned channels	Teli preferred for cost-sensitive scenarios

V. Usage Guidelines

No mixing: Avoid blending with other oils to prevent chemical degradation.
Clean handling: Use sterilized tools to prevent contamination.
Sealed storage: Use opened containers promptly; store sealed to avoid oxidation.
Regular testing: Monitor acid value, viscosity, and replace as needed (refer to equipment manuals).
Moisture control: Prevent water ingress (causes corrosion, icing, additive failure).

VI. R&D & Production Strengths

R&D: Supported by Aero Engine Engineering Technology Research Center, with a team of 4 PhDs and senior engineers.
Global collaboration: Partners include Southwest Research Institute (SWRI, USA) and AVL Europe.
Production: Advanced refining and dewaxing processes ensure high-purity base oil.

VII. Market Positioning & Competitiveness

Cost advantage: 10–15% lower price than Kunlun Sky Type; even greater savings for ground-use variants.
Client base: Strategic clients include AECC, CASIC, and PLA military-industrial giants.
Certifications: Approved by the National Committee for Naval/Aviation Oil Certification; complies with military/national standards.

Summary & Recommendations

Teli 10 Aviation Hydraulic Oil (Sky Type) stands out for its extreme low-temperature adaptability, stability, and cost efficiency, making it a strong contender in aviation hydraulic oil markets. Key applications include:

Military: Non-mandatory state-brand scenarios (e.g., civil-military integration projects).
Civil aviation: General aircraft, polar-region ground equipment.
Specialized machinery: Arctic expedition gear, high-pressure hydraulic systems.

Selection advice:

For equipment using Kunlun oil, validate compatibility before switching to Teli for cost savings.
Prioritize Teli Sky Type in ultra-low-temperature environments (below -70°C).
Adhere to state-owned procurement policies for military use; flexibility in civilian sectors.
