Key Uses in High-End Lubricants
T512’s versatility makes it a cornerstone in a range of high-temperature lubricant formulations. International formulators rely on it for:
1. High-End Hydraulic Oil
Protects hydraulic systems operating under high pressure and temperature, preventing oil degradation and ensuring smooth operation of industrial machinery.
2. Gear Oil
Resists oxidation in heavy-duty gear systems (e.g., industrial gears, automotive transmissions), reducing wear and extending gear life—paired with Antiwear EP Additive (T321) for enhanced load-carrying capacity.
3. Engine Oil (ICE Oils)
Ideal for gasoline and diesel engine oils (PCMO, HDEO), combating oxidation from combustion heat and maintaining oil viscosity over extended drain intervals.
4. Heat Conducting Oil
Withstands continuous high temperatures in thermal transfer systems, ensuring stable heat distribution and long oil service life.
5. High-Temperature Chain Oil
Protects industrial chains in high-heat environments (e.g., manufacturing, processing plants) from oxidation and wear.
6. Custom Additive Packages
Serves as a core component in tailored additive packages, including hydraulic oil additive packages, gear oil additive packages, and engine oil additive packages.
Compatibility & Synergy with Chorus Core Additives
T512’s excellent compatibility is a major advantage for formulators—blending seamlessly with 6+ Chorus core additives to create high-performance packages:
- Ashless Dispersant (T151): Combines to prevent sludge and deposit formation, keeping lubricants clean and engines protected.
- Antiwear EP Additive (T321): Enhances anti-wear and extreme pressure performance, ideal for gear oil and hydraulic oil formulations.
- Rust Preventative Anti-rust Additive (Chorus-404): Amplifies corrosion protection, critical for lubricants used in humid or harsh environments.
- Pour Point Depressant (T248): Maintains low-temperature fluidity while T512 preserves high-temperature stability—creating all-season lubricants.
- TBN Booster Calcium Sulfonate (T105): Balances acid neutralization and oxidation resistance, perfect for engine oil formulations.
- Corrosion Inhibitor ZDDP (T202): Adds anti-corrosion and anti-wear benefits, complementing T512’s oxidation protection for comprehensive lubricant performance.
Pro Tip: For maximum oxidation resistance, compound T512 with High Temperature Antioxidant (T536 P,p'-Dinonyl Diphenylamine Antioxidant)—the synergistic effect significantly extends lubricant service life.
How to Incorporate T512 into Lubricant Formulations
Follow these structured steps to ensure optimal performance when using T512 in your additive packages:
- Determine Treat Rate: Use 0.3-0.5% by weight based on your lubricant type (e.g., 0.3% for hydraulic oil, 0.5% for high-temperature chain oil).
- Select Complementary Additives: Pair T512 with Ashless Dispersant (T151), Antiwear EP Additive (T321), and Rust Preventative Additive (Chorus-404) based on formulation goals.
- Blend in Correct Sequence: First mix base oil, add T512, then incorporate other additives (dispensants, antiwear agents, rust inhibitors) to ensure uniform dispersion.
- Control Temperature: Maintain blending temperature below 65℃ to preserve additive integrity (consistent with Chorus’s handling guidelines).
- Test Performance: Validate oxidation resistance via ASTM D943 (Oxi-Pressure Test) and thermal stability via differential scanning calorimetry (DSC).
- Scale Production: Once lab tests are successful, scale to bulk production while adhering to storage and transportation temperature limits (≤45℃).
