Description

Didodecyl Azelate is a high-purity diester derived from azelaic acid and dodecanol, valued for its excellent lubricity and stability. This compound serves as a critical performance additive and intermediate in advanced formulations, offering superior solvency and low volatility. It is essential for manufacturers in the lubricants, plastics, and specialty chemical industries seeking to enhance product performance and longevity.

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 excellent thermal and oxidative stability.
• Plasticizer for Polymers: Acts as a secondary plasticizer and lubricant in PVC, cellulose esters, and synthetic rubbers to improve flexibility and processing characteristics.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex esters, surfactants, and corrosion inhibitors.
• Functional Fluid Formulations: Employed in high-temperature hydraulic fluids, heat transfer fluids, and dielectric fluids due to its low pour point and high flash point.
• Cosmetic & Personal Care Ingredient: Functions as an emollient and skin-conditioning agent in premium cosmetic formulations.
• Metalworking Fluid Component: Incorporated into cutting oils and drawing compounds as a lubricity enhancer and extreme pressure (EP) additive.
