Products Description
Dioctyl terephthalate DOTP, a water-insoluble but organically soluble oily liquid, serves as a premium PVC plasticizer. It outperforms DOP with enhanced thermal stability, low volatility, migration resistance, electrical insulation, and sustained flexibility, especially in low-temperature and soap-resistant applications.
