Low-TBN Calcium Sulfurized Alkylphenate
Low-TBN calcium sulfurized alkylphenate — a phenate detergent contributing high-temperature detergency and antioxidancy, used where moderate base and strong deposit control are needed.
The phenate detergent for high-temperature cleanliness
Sulfurized alkylphenate detergents are prized for high-temperature detergency and a useful antioxidant contribution from their sulphur bridges — the low-TBN grade brings these with moderate base.
Calcium sulfurized alkylphenate is a phenate detergent that excels at high-temperature detergency — keeping pistons and ring grooves clean under thermal stress — while the sulphur in its structure also provides antioxidant function. The low-TBN grade supplies these benefits with a moderate base reserve, suited to formulations that need phenate detergency and antioxidancy without high TBN. Phenates are typically used together with sulfonate and salicylate detergents to balance TBN, cleanliness and antioxidancy.
Low-TBN Calcium Sulfurized Alkylphenate — typical properties
Representative typical values for low-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) | ~100–150 mg KOH/g | ASTM D2896 · grade-dependent |
| Calcium content | ~3.5–5.5 wt% | Grade-dependent |
| Sulphur content | Present (active) | Provides antioxidancy |
| Kinematic viscosity (100°C) | ~80–250 mm²/s | ASTM D445 |
| Flash point (COC) | > ~170 °C | ASTM D92 |
| Density (15°C) | ~1.0–1.15 g/cm³ | Typical |
