1. Product Description
Dioctyl Terephthalate (DOTP), with CAS No 6422-86-2 (also known as bis(2-ethylhexyl) terephthalate), is a high-performance, non-phthalate plasticizer derived from terephthalic acid. This colorless to light-yellow liquid is widely used by DOTP suppliers, factories and manufacturers as an eco-friendly alternative to traditional plasticizers.
As a leading DOTP plasticizer supplier in China, Integratechem synthesizes this compound from terephthalic acid and octanol, ensuring superior flexibility and durability in PVC applications.
Chemical Composition:
- Molecular Formula: C₃₆H₆₈O₄
- Molecular Weight: 390.56
