Diundecyl Phthalate

Description:
Diundecyl phthalate (DUP) is an ester derived from phthalic acid and undecanol, characterized by its long hydrocarbon chains. It is a colorless to pale yellow liquid with a low volatility and a relatively high boiling point, making it suitable for various applications. DUP is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers, enhancing their flexibility, durability, and processability. Its chemical structure contributes to its low toxicity and good compatibility with a range of materials. Additionally, diundecyl phthalate exhibits good thermal stability and resistance to extraction, which is advantageous in applications requiring long-term performance. However, like other phthalates, it has raised environmental and health concerns, leading to regulatory scrutiny regarding its use. Overall, diundecyl phthalate is valued in industrial applications for its performance characteristics, but its environmental impact necessitates careful consideration in its use and disposal.
