Diisooctyl phthalate

Description:
Diisooctyl phthalate (DOP), with the CAS number 131-20-4, is a colorless to pale yellow liquid that is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers. It enhances the flexibility, durability, and workability of plastic materials. DOP is characterized by its low volatility, good thermal stability, and resistance to extraction by water, making it suitable for various applications, including coatings, adhesives, and sealants. The substance has a relatively high molecular weight and a low glass transition temperature, contributing to its effectiveness as a plasticizer. However, concerns regarding its potential health effects and environmental impact have led to regulatory scrutiny and a shift towards alternative plasticizers in some applications. DOP is also known for its compatibility with a wide range of polymers, which allows for its use in diverse formulations. Overall, while it remains a widely used plasticizer, ongoing research and regulation may influence its future use in industry.
