Description

Dodecanedioic Acid Di(2-Ethylhexyl) Ester is a high-molecular-weight diester plasticizer derived from dodecanedioic acid. This compound is valued for its excellent permanence, low volatility, and compatibility with a wide range of polymers, providing enhanced flexibility and durability. It is primarily sought by manufacturers in the plastics, coatings, and specialty lubricants industries seeking superior performance in demanding applications.

Application

• Primary plasticizer for polyvinyl chloride (PVC), polyurethane (PU), and other polymers requiring low migration and high-temperature stability.
• Functional additive in specialty lubricants and greases to improve viscosity index and low-temperature performance.
• Coalescing agent and plasticizer in high-performance coatings, adhesives, and sealants to enhance film formation and elasticity.
• Intermediate in the synthesis of specialty polymers, resins, and lubricant additives.
• Plasticizer for wire and cable insulation, automotive interiors, and other applications demanding long-term flexibility.
• Additive in cosmetic and personal care formulations (e.g., nail polish) as a film-forming agent and plasticizer.
