150 TBN Synthetic Calcium Sulfonate: Uses in Medium Lube Formulas

For international lubricant formulators and procurement professionals, medium-grade lubricants demand a balance of performance, cost-efficiency, and versatility. At the heart of reliable medium lube formulas lies 150 TBN Synthetic Calcium Sulfonate—a high-performance metal detergent that delivers critical detergency, rust protection, and acid neutralization. Chorus’s 150 TBN Synthetic Calcium Sulfonate (Medium Lube Additive T105) is engineered to meet the rigorous demands of modern lubricant formulations, making it a go-to choice for blending internal combustion engine (ICE) oils, rust-preventing oils, and custom additive packages. Below, we break down its key uses, technical advantages, and how it integrates with other core additives to elevate medium lubricant quality.

Core Composition & Manufacturing

Chorus’s T105 is a medium-based synthetic calcium sulfonate, part of the sulfonate salt series of lubricant additives. It is produced via neutralization and alkalization reactions using linear long-chain alkylbenzene sulfonic acid—ensuring consistent purity and performance across batches, a top priority for international buyers.

Key Performance Benefits for Medium Lubes

• Exceptional acid neutralization capacity: Neutralizes organic/inorganic acids generated during lube operation, extending oil service life and reducing equipment wear.
• Reliable antirust property: Shields metal components from corrosion, critical for medium lubes used in harsh or humid environments.
• Superior high-temperature detergency: Prevents carbon deposits, varnish, and sludge buildup in ICEs, maintaining equipment efficiency.
• Versatile TBN booster: Delivers a 150 TBN baseline, enhancing lube longevity and compatibility with other additives.
• Cost-effective versatility: Ideal for medium-grade formulations without compromising on performance.
  
  

Chorus’s T105 adheres to international ASTM standards, providing transparent, verifiable performance metrics for global procurement:

• Density (20℃): 1015 kg/m³ (Test Method: ASTM D4052)
• Kinematic Viscosity (100℃): 25 mm²/s (Test Method: ASTM D445)
• Flash Point (COC): 200℃ (Test Method: ASTM D92)
• Total Base Number (TBN): 165 mgKOH/g (Test Method: ASTM D2896)
• Calcium (Ca) Content: 6.6 m% (Test Method: ASTM D4951)
• Sulfur (S) Content: 1.9 m% (Test Method: ASTM D1552)
• Water Content: 0.05 m% (Test Method: ASTM D95)

1. Internal Combustion Engine (ICE) Oils

T105 is a staple in medium-grade ICE oil formulations, including:

• Passenger Car Motor Oil (PCMO) for everyday vehicles
• Heavy-Duty Diesel Engine Oil (HDEO) for light to medium-duty trucks
• 4T Motorcycle Oil for standard-performance motorcycles

Its acid neutralization and high-temperature detergency keep engines clean and protected under moderate to heavy loads.

2. Rust-Preventing Oils

Blended alone or with other additives, T105 creates effective rust-preventing oils for metal parts storage and transportation—ideal for automotive, industrial, and marine components.

3. Custom Additive Packages

As a versatile TBN booster, T105 forms the foundation of tailored additive packages, such as:

• Hydraulic Oil Additive Package (for medium-pressure hydraulic systems)
• Gear Oil Additive Package (for industrial and automotive gears)
• Multi-Purpose Lubricant Additive Package (for cross-industry applications)

T105’s performance is amplified when blended with Chorus’s complementary lubricant additives—critical for formulating high-quality medium lubes. Key pairings include:

• Ashless Dispersant (T151): Enhances sludge and deposit control, ensuring lube cleanliness in extended service intervals.
• ZDDP (T202): Adds anti-wear and corrosion inhibition, protecting engine bearings and metal surfaces from friction damage.
• High Temperature Antioxidant (T512): Boosts thermal stability, preventing lube oxidation at high operating temperatures.
• Antiwear EP Additive (T321): Improves load-carrying capacity, making medium lubes suitable for heavy-load gear and hydraulic systems.
• Rust Preventative Additive (Chorus-404): Amplifies rust protection, ideal for lubes used in corrosive environments.
• Pour Point Depressant (T248): Enhances low-temperature fluidity, ensuring medium lubes perform reliably in cold climates.

Follow these structured steps to achieve optimal results when blending T105 into your medium lubricant formulations:

1. Define Formulation Goals: Identify target application (e.g., PCMO, hydraulic oil) and performance requirements (e.g., TBN level, rust protection).
2. Select Complementary Additives: Pair T105 with Chorus’s Ashless Dispersant (T151), ZDDP (T202), and Antiwear EP Additive (T321) based on your goals.
3. Determine Treat Rates: For medium lubes, T105 is typically used at 3-7% (by weight). Adjust based on desired TBN and detergency levels.
4. Blend in Sequence: First mix base oil, add T105, then incorporate antioxidants and antiwear additives, followed by dispersants and pour point depressants.
5. Test Performance: Validate key metrics (TBN retention, rust protection, high-temperature stability) using ASTM-standard tests.
6. Scale Production: Once validated, scale blending while maintaining consistent temperatures (≤65℃) and storage conditions.

For international buyers seeking a reliable, high-performance additive for medium lube formulas, Chorus’s T105 delivers unmatched value: ASTM-certified quality, versatile applications, seamless compatibility with core additives, and logistics-friendly packaging. Whether you’re formulating ICE oils, rust-preventing oils, or custom additive packages, T105 is the key to creating medium lubes that balance performance, cost, and durability.
