Description

Diethyl Azelate is a high-purity diester of azelaic acid, valued for its excellent solvency and plasticizing properties. This versatile chemical intermediate is crucial for formulators seeking a low-volatility, high-performance additive with good compatibility in various polymer systems. It is primarily used by manufacturers in the plastics, lubricants, and specialty chemical industries to enhance product flexibility, stability, and processing characteristics.

Application

• Plasticizer for Polymers: Acts as an efficient, low-volatility plasticizer for PVC, polyurethanes, and synthetic rubbers, improving flexibility and low-temperature performance.
• Lubricant and Synthetic Oil Base Stock: Serves as a key component in the formulation of synthetic lubricants, greases, and hydraulic fluids due to its thermal stability and low pour point.
• Chemical Intermediate: Used in organic synthesis for the production of polyesters, polyamides, and other specialty polymers.
• Solvent and Carrier: Functions as a high-boiling-point solvent in coatings, inks, and adhesive formulations.
• Cosmetic and Personal Care Ingredient: Employed as an emollient and skin-conditioning agent in high-end cosmetic formulations.
• Fuel and Lubricant Additive: Enhances the cold-flow properties and oxidative stability of biodiesel and other fuel blends.

Quality Control

Our Diethyl Azelate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for industrial and specialty applications. Certificates of Analysis (COA) are provided with each shipment to guarantee consistent quality, traceability, and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases 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 contamination.
