High-TBN Calcium Sulfurized Alkylphenate
High-TBN calcium sulfurized alkylphenate — a high-base phenate combining strong acid neutralization with the high-temperature detergency and antioxidancy phenates are known for. For demanding diesel and marine oils.
The high-base phenate for demanding engine oils
High-TBN calcium sulfurized alkylphenate combines a strong base reserve with the high-temperature detergency and antioxidancy phenates are valued for — ideal for hard-working diesel and marine oils.
The high-TBN grade of calcium sulfurized alkylphenate delivers strong acid neutralization alongside the high-temperature detergency and antioxidant function characteristic of phenates. This makes it well suited to demanding diesel and marine engine oils that run hot, see high deposit loads and need both base reserve and oxidation protection. It works in concert with high-TBN sulfonate detergents and is part of the sulfurized alkylphenate family.
High-TBN Calcium Sulfurized Alkylphenate — typical properties
Representative typical values for high-TBN calcium sulfurized alkylphenate. Indicative only — exact values vary by grade and are confirmed on the TDS and batch COA.
| Property | Typical Value | Method / Note |
|---|---|---|
| Appearance | Brown viscous liquid | Visual |
| Total Base Number (TBN) | ~250–300 mg KOH/g | ASTM D2896 · grade-dependent |
| Calcium content | ~8–10 wt% | Grade-dependent |
| Sulphur content | Present (active) | Provides antioxidancy |
| Kinematic viscosity (100°C) | ~100–350 mm²/s | ASTM D445 |
| Flash point (COC) | > ~170 °C | ASTM D92 |
| Density (15°C) | ~1.1–1.25 g/cm³ | Typical |
Typical values for guidance only — not a specification. Request the TDS for the specific grade you need; the COA reports actual measured values for your batch.
Where high-TBN calcium phenate is used
Diesel Engine Oils
High base reserve plus high-temperature detergency for hard-working diesel pistons. See diesel engine oil.
Marine Engine Oils
Deposit control and antioxidancy with strong TBN for marine engines. See industrial & marine.
Heavy-Duty PCMO
High-temperature cleanliness and base reserve for demanding passenger car oils.
Detergent Systems
Combined with high-TBN sulfonate for balanced TBN and antioxidancy.
Why formulators choose high-TBN calcium phenate
Strong base + detergency
High TBN reserve combined with the phenate's high-temperature cleaning power.
Antioxidant strength
Active sulphur delivers strong oxidation protection for long-drain oils.
Built for demanding oils
Ideal where pistons run hot and oxidation and deposits are most challenging.
