T321H Sulfurized Isobutylene (High-pressure Synthesis)

Product Overview

This additive is synthesized via a high-pressure reaction process, presenting as a pale yellow transparent liquid. It serves as a key sulfur-based component in gear oil formulations.

Key Characteristics

• 
  
• Outstanding extreme pressure performance with strong anti-welding properties, preventing tooth surface damage under high-impact loads.
• Under high friction temperatures, its decomposition products react with metal surfaces to form a protective chemical film, reducing wear and scuffing risks.
• Exhibits superior solubility in both mineral and synthetic base oils, maintaining stability without precipitation during prolonged storage.

Applications & Dosage

Widely used in the formulation of various gear oils, metalworking fluids, and other lubricants.

Recommended dosage: 1.5–5.0%
