Description

Decanedioic Acid Bis[2-(2-Butoxyethoxy)Ethyl] Ester is a high-purity, high-molecular-weight diester plasticizer derived from sebacic acid. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior low-temperature flexibility and resistance to extraction. It is primarily sought after by formulators in the plastics, coatings, and specialty lubricant industries seeking to enhance product performance and durability.

Application

• Primary Plasticizer for PVC, polyurethanes, and synthetic rubbers, imparting excellent low-temperature flexibility and durability.
• Functional Additive in high-performance lubricants and greases to improve viscosity index and thermal stability.
• Coalescing Agent & Plasticizer in specialty polymer dispersions, latex paints, and adhesive formulations.
• Intermediate for the synthesis of more complex ester-based compounds and polymeric materials.
• Component in sealants, caulks, and gaskets where long-term flexibility and resistance to migration are critical.
