Dioctyl Terephthalate Plasticizer
Eco-friendly phthalate-free plasticizer — the sustainable replacement for DOP in modern PVC formulations.
DOTP (Dioctyl Terephthalate) is a high-performance, phthalate-free plasticizer that serves as a direct drop-in replacement for DOP. Offering comparable plasticizing efficiency with superior heat resistance, lower volatility, and better UV stability, DOTP is the preferred choice for eco-conscious manufacturers and applications requiring long-term durability.
Key Features
Phthalate-free — REACH and RoHS compliant
Superior heat and UV resistance vs DOP
Lower volatility — reduced fogging and migration
Excellent electrical insulation properties
Compatible with all flexible PVC grades
Better low-temperature performance
