DOA Adipate
DOA Adipate, or Bis(2-ethylhexyl) adipate, is a highly effective, low-toxicity secondary plasticizer widely used in various polymer systems.
Description
Bis(2-ethylhexyl) adipate (DOA) is an organic compound with the chemical formula C22H42O4 and CAS Registry Number 103-23-1. It is synthesized through the esterification of adipic acid with 2-ethylhexanol. DOA functions primarily as a plasticizer, a substance added to materials, typically plastics, to increase their flexibility, transparency, durability, and ease of processing. As a diester, it imparts excellent low-temperature flexibility, good processability, and superior weather resistance to polymeric materials. Its low volatility and extraction resistance contribute to the long-term performance of the final products. DOA is particularly noted for its compatibility with a wide range of polymers, including PVC, cellulose resins, and synthetic rubbers, making it a versatile additive in the plastics industry. Its molecular structure provides a balance of chain length and branching, which optimizes its plasticizing efficiency while maintaining beneficial physical properties.
Applications
DOA Adipate finds extensive application in the plastics industry, particularly in flexible PVC products where low-temperature performance is critical. It is a key component in the formulation of food packaging films, ensuring flexibility and puncture resistance even at chilled temperatures. It is also utilized in electrical cable insulation and jackets, contributing to their cold weather durability and improved processability. The automotive industry employs DOA in various interior and exterior components, such as upholstery and profiles, for enhanced flexibility and resilience. Furthermore, it is used in synthetic leather, flooring materials, and garden hoses, providing superior softness, elasticity, and resistance to environmental factors. Its low toxicity profile also makes it suitable for certain medical device applications and toys.
Storage & Handling
Store DOA Adipate in a cool, dry, well-ventilated area away from direct sunlight and sources of ignition. Keep containers tightly closed. Avoid contact with strong oxidizing agents. Use appropriate personal protective equipment during handling to prevent skin and eye contact.
