Description

Nonanedioic Acid, Bis(2-Hexyldecyl) Ester is a high-molecular-weight diester of azelaic acid, valued for its excellent lubricity, thermal stability, and plasticizing properties. This specialty chemical serves as a high-performance additive and intermediate, offering superior solvency and compatibility with a wide range of polymers and base oils. It is primarily utilized by formulators in the lubricants, plastics, and personal care industries seeking to enhance product performance and durability.

Application

• Synthetic Lubricant Base Stock & Additive: Used as a high-performance base fluid or viscosity modifier in synthetic engine oils, compressor oils, and greases, offering low volatility and excellent thermal-oxidative stability.
• Polymer Plasticizer: Acts as a secondary plasticizer or co-stabilizer in PVC and other polymer systems to improve flexibility, low-temperature performance, and processing characteristics.
• Personal Care & Cosmetic Emollient: Functions as a non-greasy, spreading emollient in skin care formulations, lipsticks, and sunscreens, providing a smooth skin feel and enhancing product texture.
• Metalworking Fluid Component: Incorporated into synthetic and semi-synthetic metalworking fluids as a lubricity agent and corrosion inhibitor for machining and grinding operations.
• Functional Fluid Additive: Employed in hydraulic fluids, heat transfer fluids, and dielectric fluids to improve lubricity, reduce wear, and enhance fluid stability.
• Adhesive & Sealant Modifier: Used to modify the rheology and improve the flexibility and adhesion of hot-melt adhesives and sealants.
