Bis(2-ethylhexyl) terephthalate

Description:
Bis(2-ethylhexyl) terephthalate (DEHT) is an ester derived from terephthalic acid and 2-ethylhexanol, commonly used as a plasticizer in various applications, particularly in polyvinyl chloride (PVC) products. It is characterized by its high molecular weight, low volatility, and excellent thermal stability, making it suitable for use in flexible plastics. DEHT is known for its ability to enhance the flexibility and durability of materials while maintaining low migration rates, which is crucial for applications in food packaging and medical devices. Additionally, it exhibits good resistance to UV light and oxidation, contributing to the longevity of products containing it. DEHT is considered a safer alternative to traditional phthalate plasticizers, as it has a lower toxicity profile and is less likely to disrupt endocrine functions. Its physical properties include a relatively high boiling point and low solubility in water, while being soluble in organic solvents. Overall, DEHT is valued for its performance and safety in various industrial and consumer applications.
