1. Core Parameters and Formulation

1. Base Formula

• Primary Components: Ethylene glycol-distilled water blend (ratio undisclosed) with antioxidants (benzotriazole derivatives) and corrosion inhibitors (e.g., phosphate complexes).

• Innovation: Employs gradient antifreeze blending technology to balance low-temperature fluidity (freezing point ≤-61.2°C) and high-temperature stability (boiling point ≥107.5°C).

2. Key Physicochemical Parameters

   Parameter	Specification	Competitor (Great Wall AF65)	Test Method
   Freezing Point	≤-61.2°C (measured)	≤-65°C (theoretical)	SH/T 0090
   Boiling Point	≥107.5°C	118°C	GB/T 255
   Density (20°C)	1.060–1.085 g/cm³	1.070–1.090 g/cm³	SH/T 0068
   Refractive Index (n20D)	1.480 (measured)	1.400 (standard)	GB/T 614
   Distillation Rate (≤150°C)	≤32% (measured)	≤35% (standard limit)	GB/T 255
   pH Value	8.5 (measured)	8.0–9.0 (standard range)	SH/T 0089
   Mechanical Impurities	≤0.035%	≤0.05%	GB/T 511

• Low-Temperature Adaptability: Achieves -61.2°C, meeting demands in northern China (-50°C to -60°C) and Russia’s Far East.

• Thermal Stability: 32% distillation rate below 150°C outperforms standards (≤35%), indicating minimal evaporation loss.

2. Standards and Certifications

1. Core Standards

• Military Compliance: Complies with GJB 6100-2007 (copper corrosion ≤ Grade 1, foam volume ≤50 mL at 88°C, pour point ≤-65°C).

• Industry Standard: Meets YSB07-2013 (missile equipment coolant standard), replacing Russian counterparts (e.g., Soviet-era No. 60 coolant).

2. Environmental Concerns

• Contains ethylene glycol (poor biodegradability); lags behind eco-friendly options like Chevron Delo ELC (nitrate-free).

3. Applications and Performance

1. Military Use

• Missile Systems: Ensures -60°C cold starts and thermal stability for C-300 missile launchers, replacing Russian imports.

• Aircraft: Cools Su-27 fighter radar systems under -60°C to +100°C thermal cycling.

• Electronics: Maintains thermal balance for radar equipment in extreme cold, preventing signal loss.

2. Civilian and Industrial Use

• Arctic Machinery: Replaces -35°C coolants in polar excavators and ATVs.

• Energy Storage Potential: Adaptable to battery thermal management (requires conductivity adjustments).

3. Advantages

• Broad Temperature Range: Operates from -60°C to +107.5°C (short-term peak 120°C).

• Longevity: 3-year service life (vs. 2 years for standard coolants).

4. Market Competition and Positioning

1. Domestic Competitors

   Brand/Model	Freezing Point	Boiling Point		Key Advantage
   Teli No. 60	-61.2°C	107.5°C		Military customization, cost-effective
   Great Wall AF65	-65°C	118°C		Ultra-low-temperature
   Tiancheng Meijia No. 60	-60°C	105°C		Civilian market focus

• Teli’s Edge: Custom specifications (No. 60/65) and flexible packaging (20 kg/drum).

2. Global Competitors

• Mobil Mobilcool 352: Full-synthetic (boiling point ≥120°C) but costs 3× higher .

• Totachi G12+ -60℃: Complies with VW TL 774-F but weaker anti-corrosion (800 vs. 1,200 hours salt spray resistance).

5. Challenges and Future Development

1. Current Limitations

• Low-Temperature Viscosity: Dynamic viscosity ≥3,500 mPa·s at -60°C impacts pump efficiency (requires pour point depressants).

• Eco-Friendliness: Explore propylene glycol or organic acid-based alternatives (e.g., Repsol CXR).

2. R&D Trends

• Full-Synthetic Upgrades: Polyether/fluorinated fluids (e.g., FEC-50) for -70°C to +150°C operation.

• Smart Monitoring: IoT sensors for real-time analysis (pH, conductivity, contaminants).

Summary and Recommendations

Teli No. 60 Coolant, compliant with GJB 6100-2007 and YSB07-2013, excels in extreme cold adaptability and military reliability. Key strengths include:

• Dual-Use Versatility: Military and civilian applications in harsh climates.

• Cost Efficiency: 15–20% cheaper than Great Wall AF65.

• Scalability: Potential in energy storage and data center immersion cooling.
