DOTP Plasticizer
DOTP Plasticizer, or dioctyl terephthalate, is a clear, colorless, and oily liquid commonly used to improve the flexibility of plastics. It has excellent long-term durability, low volatility, and good resistance to soap water. DOTP is insoluble in water but dissolves easily in organic solvents like ethanol and ether. It is widely used as a primary plasticizer for PVC products due to its stable performance and reliable electrical insulation properties.

What is DOTP Plasticizer?
Dioctyl Terephthalate (DOTP) is a widely used eco-friendly industrial plasticizer, specifically designed to enhance the flexibility, durability, and thermal stability of polyvinyl chloride (PVC) products. It is a clear, colorless, and oily liquid with excellent chemical and physical properties, making it a preferred choice in various industries.
DOTP is characterized by its low volatility, high resistance to water, and minimal extraction under harsh conditions. It offers exceptional long-term durability, superior electrical insulation, and retains excellent flexibility even at low temperatures. These properties ensure reliable performance in demanding applications.
This plasticizer finds extensive application in the manufacturing of cables, flooring materials, automotive interiors, and other high-quality PVC products. Its ability to blend seamlessly with PVC and other resins without affecting mechanical properties has established DOTP as a top-tier additive in the plastics industry.

Comparison of DOTP and DOP
| Property | DOTP | DOP |
|---|---|---|
| Chemical Composition & Environmental Impact | DOTP (Dioctyl Terephthalate) is a terephthalate-based plasticizer that is phthalate-free and environmentally friendly. It does not fall under the EU’s restricted list of phthalate plasticizers, making it a safer alternative. | DOP (Dioctyl Phthalate) is a phthalate-based plasticizer, which may pose environmental pollution risks and potential health hazards, including carcinogenicity as confirmed in animal studies. |
| Applications | Used for PVC plastics, cables (especially in high-temperature environments like 70°C cables), synthetic leather, acrylic derivatives, polyvinyl alcohol, nitrile rubber, nitrocellulose, and as a softener in paints, lubricants, and paper. | Widely used in PVC resins, synthetic fibers, acetate resins, ABS resins, rubber, and in paints, dyes, and dispersants. |
| Physical Properties | Transparent, oil-like liquid with a density of 0.981–0.986 g/cm³ and a refractive index of 1.1687. | Colorless, transparent liquid with a density of 0.982 g/cm³ and a refractive index of 1.485. |
