Dipropyl Phthalate

Dipropyl Phthalate (DPP) is a phthalate ester compound with the chemical formula C₆H₄(COOCH₂CH₂CH₃)₂. It appears as a colorless to pale yellow transparent oily liquid with a slight characteristic odor. As a typical plasticizer, it demonstrates good compatibility with a wide range of resins, effectively enhancing the flexibility, extensibility, and processability of polymers. Due to its relatively low molecular weight, it is generally more volatile than more common phthalates like Dioctyl Phthalate (DOP) or Diisononyl Phthalate (DINP). In recent years, its application has been restricted in certain areas due to health and environmental concerns.
