Description

Bis(2-Hydroxyethyl) Azelate is a versatile, high-purity diester derived from azelaic acid and ethylene glycol, serving as a key intermediate and functional additive. Its value lies in its dual hydroxyl functionality and long-chain aliphatic structure, offering excellent solvency, plasticizing effects, and reactivity for polymer synthesis. This compound is essential for manufacturers in the polymer, coatings, and specialty chemical industries seeking to enhance product flexibility, adhesion, and performance.

Application

• As a reactive diluent and building block in the synthesis of polyesters, polyurethanes, and alkyd resins.
• As a plasticizer and softening agent for PVC, synthetic rubbers, and cellulose-based polymers to improve flexibility and low-temperature performance.
• As a key intermediate for producing lubricants and synthetic esters with high thermal stability and low volatility.
• In the formulation of high-performance coatings, adhesives, and sealants to enhance durability and adhesion properties.
• As a solvent and carrier in specialty chemical and agrochemical formulations.
• In personal care and cosmetic products as a skin-conditioning agent and emollient.
