Dioctyl Terephthalate (DOTP, CAS 6422-86-2) is a premium, colorless or slightly yellowish oily liquid featuring high stability and low volatility. It is practically insoluble in water but completely miscible with major organic solvents. As a highly efficient primary plasticizer, DOTP exhibits outstanding compatibility with polyvinyl chloride (PVC) and various synthetic resins. In contrast to conventional phthalate plasticizers (such as DOP/DEHP), DOTP is free from ortho-phthalate structures, making it an eco-friendly and non-toxic alternative. Due to the unique para-position arrangement in its molecular skeleton, DOTP provides polymers with significantly superior thermal stability, excellent electrical insulation, better low-temperature flexibility, and exceptionally low migration rates. It is globally recognized as the ideal green plasticizer to substitute DOP for high-performance applications and export-oriented polymer products.

Core Applications

High-Temperature Wire & Cable Compounds: Heavily specified in manufacturing 70°C and 105°C automotive wire harnesses, optical communication cables, and insulation sheathing due to its elite dielectric resistance and low thermal evaporation.
Automotive Interiors & Synthetic Leather: Utilized in producing dashboard sealing strips, seat leathers, and interior mats to successfully mitigate windshield fogging issues and limit total volatile organic compounds (VOCs).
Eco-Friendly Flexible PVC Products: Formulated as a non-toxic and compliant alternative in food wrap packaging, medical-grade IV tubes, blood bags, consumer toys, and advanced residential flooring.
Coatings & Precision Additives: Deployed as a flexible modifying modifier and anti-cracking agent in industrial polyurethanes, high-grade adhesives, printing inks, and specialized lubricating formulations.

Packaging & Storage

Packing: Standard shipment packaging is 200 KGS net weight per drum, 1000 KGS IBC containers, or via large-scale bulk ISO TANK logistics.
Storage: Store within a cool, dry, and optimally ventilated chemical storage warehouse. Keep away from heat, sparks, open flames, and direct sunlight. Keep all containers tightly sealed and separate from powerful oxidizing substances.
