Medium-TBN Calcium Sulfurized Alkylphenate
Medium-TBN calcium sulfurized alkylphenate — a balanced phenate detergent combining strong high-temperature detergency, antioxidancy and useful TBN reserve for mainstream engine oils.
The balanced phenate for mainstream engine oils
Medium-TBN calcium sulfurized alkylphenate brings strong high-temperature detergency and antioxidancy together with a useful base reserve — the versatile phenate for mainstream formulations.
The medium-TBN grade of calcium sulfurized alkylphenate offers a balance of high-temperature detergency, antioxidant function and moderate TBN reserve. It is a versatile phenate for mainstream passenger car and diesel engine oils, contributing piston cleanliness and oxidation protection while adding to the oil's base reserve. As with all phenates, it is used together with sulfonate and salicylate detergents to optimize the overall detergent-antioxidant system.
Medium-TBN Calcium Sulfurized Alkylphenate — typical properties
Representative typical values for medium-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) | ~150–250 mg KOH/g | ASTM D2896 · grade-dependent |
| Calcium content | ~5.5–8 wt% | Grade-dependent |
| Sulphur content | Present (active) | Provides antioxidancy |
| Kinematic viscosity (100°C) | ~90–300 mm²/s | ASTM D445 |
| Flash point (COC) | > ~170 °C | ASTM D92 |
| Density (15°C) | ~1.05–1.2 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.
