Dioctyl Phthalate

Dioctyl Phthalate (DOP) is a widely used, economical general-purpose diester plasticizer known for its excellent compatibility and performance in rubber and plastics formulations. It is particularly valued in flexible polyvinyl chloride (PVC) and nitrile rubber applications, where it provides a well-balanced range of physical properties. DOP offers good stability to heat and ultraviolet light, making it a long-standing industry standard in PVC processing. In addition to its primary role as a plasticizer, DOP is also used as a solvent for various chemicals—including in glowsticks—and can serve as a component in dielectric and hydraulic fluids.
