Sulphurised olefins CAS:68515-88-8

What is PSAIL 3540?

PSAIL 3540 is a light‑colored, low‑odor, highly active sulfur‑based extreme pressure anti‑wear agent. Low viscosity and good solubility with various base oils, it exhibits excellent reactivity even at low temperature. As temperature rises, the active sulphur level of PSAIL 3540 steadily increases. This renders it suitable for heavy‑duty machining operations demanding rapid sulphur release. Furthermore, PSAIL 3540 may be blended with other phosphorus‑ and sulphur‑containing additives.

Features of PSAIL 3540

• High sulfur content: High sulfur content provides cost‑effective formulating options on a percent sulfur basis.

• Light in colour, low in odour: Characterized by light color and low odor.

• High EP performance: Provides high extreme pressure performance.

• Good compatibility: Good compatibility with various base oils, and can be blended with phosphorus‑ and sulphur‑containing additives.

• Highly active at low temperature: Exhibits excellent reactivity even at low temperature, with steadily increasing active sulphur level as temperature rises.

Functions of PSAIL 3540

• Extreme pressure & anti‑wear protection: Provides high EP performance for heavy‑duty machining operations.

• Rapid sulphur release: Steadily increasing active sulphur level with temperature, suitable for operations demanding rapid sulphur release.

• Formulation compatibility: May be blended with other phosphorus‑ and sulphur‑containing additives.
