Dioctyl Terephthalate (DOTP) has emerged as a cornerstone in modern polymer formulations, prized for its robust chemical properties and wide-ranging applications. As a leading supplier, NINGBO INNO PHARMCHEM CO.,LTD. is committed to educating our clients on the advantages of this versatile plasticizer. Understanding the chemical properties of DOTP is key to leveraging its full potential.

Chemically, DOTP is the diester of terephthalic acid and 2-ethylhexanol, with the molecular formula C24H38O4 and a molecular weight of approximately 390.56 g/mol. This structure grants it excellent thermal stability, a significantly low volatility rate, and a high resistance to migration and extraction – characteristics that are highly sought after in demanding industrial applications. When you consider the benefits of dioctyl terephthalate, these inherent chemical advantages are fundamental.

Physically, DOTP is a clear, colorless, and odorless oily liquid. Its specific gravity is around 0.98-0.99 g/cm³, and it has a high flash point, typically above 210°C, indicating its stability even under elevated temperatures. This makes it a much safer and more reliable option compared to plasticizers with lower flash points. The eco-friendly plasticizer for PVC designation is further supported by its minimal environmental impact and its classification as non-toxic.

The versatility of DOTP is one of its most significant selling points. It is widely used as a primary plasticizer for Polyvinyl Chloride (PVC), enhancing its flexibility, durability, and processing characteristics. Key application areas include:

  • Wire and Cable Insulation: DOTP's excellent electrical insulation properties and heat resistance make it ideal for high-performance cables.
  • Automotive Components: It is used in dashboards, door panels, and upholstery, providing flexibility and durability to interior parts.
  • Flooring and Wall Coverings: DOTP imparts resilience and wear resistance to vinyl flooring and wall materials.
  • Artificial Leather: It enhances the feel, flexibility, and longevity of synthetic leather products.
  • Medical Devices: Its low migration and non-toxic nature make it a preferred choice for tubing, IV bags, and other medical products.

When evaluating the DOTP vs DOP comparison, DOTP offers a superior balance of performance and safety. While DOP is a common phthalate plasticizer, concerns over its health impacts and environmental persistence have led to its gradual replacement by DOTP. DOTP’s non-phthalate status, combined with its superior technical attributes, makes it the preferred choice for manufacturers adhering to stricter regulations and seeking higher-quality end products.
