Dioctyl terephthalate (DOTP) is a PVC plasticizer with excellent properties and wide applications. It is a transparent and colorless oily liquid specially designed to replace traditional DOP. This PVC plasticizer is famous for its excellent heat resistance, cold resistance, anti-volatility and excellent electrical insulation properties. Its electrical insulation (volume resistivity) can reach 20 times that of traditional DOP, and its flash point is higher. At the same time, DOTP does not contain phthalates and is a green and environmentally friendly product that complies with international environmental regulations such as the European Union. This PVC plasticizer is widely used in a variety of PVC soft products such as temperature-resistant wire and cable materials, artificial leather, films, tapes, building materials, etc. at 70℃ and above, and its comprehensive properties comprehensively exceed traditional plasticizers.

PVC Plasticizer DOTP vs DOP :
| Performance Indicator | DOTP | DOP | Performance Interpretation & Advantages |
|---|---|---|---|
| Volume Resistivity (20°C) | Approx. 4.6 × 10¹¹ Ω·cm | Approx. 1.9 × 10¹¹ Ω·cm | Superior electrical insulation, about 2-20 times that of DOP, especially suitable for wires and cables with high insulation requirements. |
| Flash Point | 210°C (open cup) | 190°C (open cup) | Higher flash point, safer for processing and use. |
| Volatility | Low | Relatively high | Better heat aging resistance and longer product service life. Mass loss rate is lower than DOP when heated at 120-180°C. |
| Low-Temperature Resistance | Good (Freezing point -48°C) | Good (Freezing point -50°C) | Both exhibit good low-temperature performance and are comparable. |
| Toxicity/Environmental Profile | Phthalate-free, fewer regulatory restrictions | Belongs to phthalate class, subject to regulatory restrictio |
| Application Category | Specific Products / Fields | Core Advantages Demonstrated |
|---|---|---|
| Core PVC Products | Wire and Cable Compounds: Especially those rated for 70°C and above. Synthetic Leather & Films: e.g., sofa upholstery, bag material, various soft films. Molded Products & Building Materials: Including flooring, wallpaper, sealing strips. Rubberized Fabrics, Gloves, Footwear. |
High insulation, heat resistance, low volatility ensure safety and durability of cables under high temperatures; good flexibility and durability enhance the texture and lifespan of leather and film products. |
| Specialty & Emerging Applications | Medical Devices: e.g., blood bags, medical tubing. Children’s Toys & Food Contact Materials. Coatings, Paints & Lubricants. Plasticizer for materials like Nitrile Rubber, Nitrocellulose. |
Non-toxic, eco-friendly, compliant with stringent regulations (e.g., EU REACH), avoiding restrictions of traditional phthalate plasticizers. Good compatibility with various material systems. |
| Environmental & Regulatory Advantages | Suitable for all export products and high-end consumer goods with high requirements for environmental compliance. | Its non-phthalate chemical structure is its primary competitive advantage in the environmental field. |
| Packaging Container | Common Specifications | Suitable Transport Modes | Notes & Characteristics |
|---|---|---|---|
| Steel Drum (Internally plastic-coated or galvanized) | 200 kg (typical) | Suitable for road, rail, and sea freight | The most mainstream method. Internal coating prevents corrosion. Compliant with standards like GB/T 325.1, offering robustness and excellent sealing. |
| IBC (Intermediate Bulk Container) / Tote | Approx. 1000 L (approx. 1 metric ton) | Suitable for road, rail, and sea freight | Ideal for bulk transport, improves loading/unloading efficiency and reduces per-unit cost. Reusable but requires proper cleaning. |
| ISO Tank (Tank Container)
|
Approx. 20,000 L | Primarily for sea and rail freight | Used for very large-volume liquid chemical shipments. Offers high capacity and cost efficiency but requires dedicated loading/unloading infrastructure. |
