Description

Trioleyl Phosphate is a high-purity organic phosphate ester derived from oleyl alcohol, serving as a versatile and effective non-ionic surfactant and lubricant additive. Its unique molecular structure provides excellent emulsifying, anti-wear, and extreme pressure properties, making it a critical performance enhancer in demanding formulations. This compound is essential for manufacturers in the lubricants, metalworking fluids, plastics, and textile industries seeking to improve product stability and functionality.

Application

• Primary lubricant additive and anti-wear agent in synthetic and semi-synthetic industrial oils and greases.
• Key component in metalworking fluids, providing extreme pressure (EP) properties and lubrication in cutting, grinding, and stamping operations.
• Plasticizer and internal lubricant in PVC and other polymer processing to improve flexibility and mold release.
• Emulsifier and stabilizer in textile processing aids and fiber lubricants.
• Functional additive in corrosion inhibitor formulations for industrial water treatment.
• Base material for the synthesis of other specialty phosphate esters and surfactants.
• Demulsifier component in crude oil processing and petroleum refining.
• Additive in hydraulic fluids and fire-resistant hydraulic formulations.

Quality Control

Our Trioleyl Phosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. Each lot is tested against rigorous in-house specifications, which typically include assay, acid value, moisture content, and color. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and oxidation.
