Description

Lithium Isooctadecanoate is a lithium salt of a branched-chain fatty acid, valued for its role as a versatile and effective metal soap. This compound is a key component in the formulation of high-performance lubricating greases and specialty thickeners. It is essential for industries requiring stable, high-temperature, and water-resistant lubricants, such as automotive, aerospace, and heavy machinery manufacturing.

Application

• Primary thickener and structure-forming agent in multi-purpose lithium complex greases.
• Key component in high-temperature and extreme-pressure (EP) lubricating greases for automotive and industrial bearings.
• Additive in specialty lubricants for aerospace and military applications requiring wide operational temperature ranges.
• Soap-based thickener in synthetic and semi-synthetic grease formulations.
• Stabilizer and gelling agent in other non-lubricant formulations requiring metal soap rheology modifiers.
• Intermediate in the synthesis of other organometallic compounds and catalysts.

Quality Control

Our Lithium Isooctadecanoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, chemical composition, and performance characteristics relevant to grease thickening applications. A comprehensive Certificate of Analysis (COA) detailing assay, moisture content, and acid value is provided with every shipment to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture.
