Description

Fatty Acids, C18-Unsatd., Dimers, 2-Ethylhexyl Esters is a high-performance, synthetic ester derived from the dimerization of unsaturated C18 fatty acids and subsequent esterification with 2-ethylhexanol. This compound matters as a premium, non-reactive plasticizer and lubricant base, offering excellent thermal stability, low volatility, and compatibility with a wide range of polymers and formulations. It is essential for manufacturers in the plastics, lubricants, coatings, and adhesives industries seeking to enhance product flexibility, durability, and performance under demanding conditions.

Application

• Polymer Plasticizer: A primary plasticizer for PVC, synthetic rubbers, and other polymers, improving flexibility, low-temperature performance, and resistance to extraction.
• Lubricant & Metalworking Fluid: Serves as a synthetic base oil or additive in high-performance lubricants, greases, and metalworking fluids, providing excellent lubricity and oxidation stability.
• Coating & Ink Formulation: Used as a modifying agent in coatings, inks, and adhesives to adjust viscosity, enhance gloss, and improve substrate wetting and adhesion.
• Sealant & Caulk: Imparts permananent flexibility and weatherability to construction and automotive sealants and caulks.
• Personal Care & Cosmetics: Functions as an emollient and skin-conditioning agent in cosmetic formulations, valued for its non-greasy feel and good spreadability.
• Functional Fluid: Employed as a component in heat transfer fluids, hydraulic fluids, and other specialty industrial fluids.

Quality Control

Our Fatty Acids, C18-Unsatd., Dimers, 2-Ethylhexyl Esters is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency and meets specifications for critical parameters such as acid value, saponification value, color, and viscosity. Certificates of Analysis (COA) documenting these results are available upon request. Our production and quality processes are designed to support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong oxidizing agents and heat sources. Recommended storage temperature is between 15°C and 25°C. This material is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is advised for optimal long-term stability.
