I. Product Overview

Kunlun 8A Aviation Lubricant (Code: HP-8A) is a specialized lubricant produced by China National Petroleum Corporation (CNPC) under the "Kunlun" brand. It complies with the GB439-1990 national standard and is designed for turbojet engines in military aircraft operating in cold regions. The lubricant demonstrates excellent low-temperature start-up performance and high-temperature stability .

II. Core Features & Technical Specifications

1. Base Oil & Additives

• Petroleum-based base oil refined from crude oil or wax-cracked olefins, enhanced with antioxidant additives .

• Compared to 8B (synthetic hydrocarbon base oil), 8A has slightly inferior low-temperature performance but lower costs .

2. Key Performance Metrics

• Operating Temperature Range: -45°C to 120°C .

• Viscosity Ratio (ν-20°C/ν50°C): ≤0.04 .

• Pour Point: -45°C (8B achieves below -60°C) .

• Flash Point: ≥120°C, ensuring safety under high temperatures .

3. Packaging

• Standard 170kg/barrel (some suppliers offer 160kg or 200L variants) .

III. Applications & Usage Guidelines

1. Primary Applications

• Lubrication for turbojet engines in fighters, trainers, and bombers .

• Mixed with No. 20 piston engine oil for turboprop aircraft (requires strict ratio testing) .

2. Critical Restrictions

• Do not mix with 8B: 8B uses synthetic hydrocarbons, offering superior performance (e.g., 50% lower viscosity at -45°C) .

• Color Changes: Darkening under prolonged high temperatures or light exposure is normal and does not affect functionality .

IV. Production & Supply Chain

1. Manufacturers

• Lanzhou Lubricant Plant: Originally produced 8A; now focuses on 8B .

• Fushun Refinery: Maintains limited 8A production capacity .

2. Market Availability

• Authorized Distributors: with direct factory shipments .

• Pricing: varies by order volume and supplier.

V. Comparison with 8B Lubricant

VI. Storage & Maintenance

1. Storage Requirements

• Store in clean, dry, and ventilated indoor areas to prevent contamination by moisture or dust .

• Keep away from ignition sources to avoid volatilization .

2. Transportation

• Follow SH0164 standards for packaging and logistics to ensure seal integrity .

VII. Procurement Recommendations

1. Supplier Verification

• Confirm authorization status and avoid prepayments to personal accounts .

2. Technical Support

• Contact manufacturer technical teams (e.g., Lanzhou Plant ) for updated specifications and compatibility guidance.

Summary

Kunlun 8A Aviation Lubricant remains a cost-effective solution for turbojet engines in cold regions, despite being outperformed by 8B in extreme conditions. Users must adhere strictly to operational guidelines and prioritize authorized suppliers to ensure safety and performance.
