Description :

Overview of Dioctyl Terephthalate

Dioctyl Terephthalate is a high-performance, non-phthalate plasticiser widely used in polymer and plastic processing. It is valued for its excellent thermal stability, low volatility, and strong compatibility with PVC and other polymer systems. Due to its molecular structure, it provides long-lasting flexibility and improved durability in finished products.

Industrial specifications commonly reference properties such as dioctyl terephthalate molecular weight, dioctyl terephthalate CAS no, dioctyl terephthalate structure, and dioctyl terephthalate solubility to ensure proper formulation control. Its balanced performance profile makes Dioctyl Terephthalate suitable for applications requiring stability under heat and long service life.

Application of Dioctyl Terephthalate

Plasticiser in PVC & Polymer Systems

Dioctyl Terephthalate is extensively used as a primary plasticiser in PVC and polymer formulations, where it enhances flexibility, toughness, and resistance to migration. It improves elongation and mechanical stability while maintaining performance under elevated temperatures.

In such systems, it is often used alongside plasticisers such as Dioctyl Adipate to fine-tune low-temperature flexibility and processing behaviour. These applications are closely aligned with requirements in PVC plastic manufacturing, where durability, safety, and long-term flexibility are critical.

Flexible Products, Cables & Industrial Components

In the production of flexible PVC products, Dioctyl Terephthalate supports consistent melt flow and uniform dispersion of additives. It is widely applied in cables, hoses, sheets, profiles, and moulded components that require stable electrical and mechanical performance.

Depending on end-use requirements, it may be blended with alternatives like Diisononyl Phthalate to optimise flexibility, cost efficiency, and regulatory compliance. These applications align strongly with polymers, where controlled plasticization and thermal resistance are essential.

Rubber & Speciality Elastomer Applications

Dioctyl Terephthalate is also used in rubber and elastomer formulations to improve softness, flexibility, and processing stability. It supports better filler dispersion and helps maintain elasticity over extended service periods.

In speciality formulations, it may be selected where low volatility and long-term performance are required, making it suitable for industrial rubber goods and elastomeric components exposed to heat and mechanical stress.

Safety and Handling Guidelines
