Dioctyl Terephthalate (DOTP) has rapidly established itself as a leading plasticizer in the chemical industry, prized for its exceptional performance characteristics and its status as a safer, non-phthalate alternative. Understanding the specific DOTP chemical properties is crucial for manufacturers seeking to optimize their formulations and product outcomes. NINGBO INNO PHARMCHEM CO.,LTD. offers high-purity DOTP, backed by comprehensive technical data, enabling businesses to fully leverage its capabilities.

At its core, DOTP is an organic compound with the chemical formula C₂₄H₃₈O₄. It is synthesized through the esterification of terephthalic acid with 2-ethylhexanol. This process results in a clear, colorless, and odorless viscous liquid at room temperature. Key physical and chemical properties that define DOTP's utility include:

  • Purity: Typically, DOTP exhibits a high purity level, often exceeding 99.5%, ensuring consistent performance and minimal unwanted side reactions in formulations.
  • Low Volatility: This property is critical for long-term product performance. Low volatility means DOTP is less likely to evaporate from the polymer matrix, maintaining flexibility and durability over extended periods.
  • Thermal Stability: DOTP demonstrates excellent resistance to heat, maintaining its plasticizing effect and structural integrity even at elevated temperatures. This is crucial for applications involving heat processing or high operating temperatures.
  • Low-Temperature Flexibility: Unlike some plasticizers that become brittle at low temperatures, DOTP helps PVC products retain their flexibility even in cold environments, expanding their application range.
  • Resistance to Extraction: DOTP shows good resistance to extraction by water, soaps, and other chemicals. This enhances the longevity and maintainability of products like cables and flooring.
  • Electrical Insulation Properties: DOTP is an excellent electrical insulator, making it a vital component in the production of wire and cable insulation where safety and performance are paramount.
  • Phthalate-Free Nature: As a terephthalate, DOTP is free from the regulatory scrutiny and health concerns associated with phthalate plasticizers, offering a safer and more compliant option.

These properties translate into a broad spectrum of applications across various industries. In the realm of wire and cable manufacturing, DOTP for cable insulation provides the necessary flexibility, electrical resistance, and durability required for safe and reliable performance. The construction industry benefits significantly from DOTP for flooring and wall coverings, where it enhances wear resistance, resilience, and aesthetic longevity. The automotive sector utilizes DOTP in interior components such as dashboards and door panels to ensure flexibility and durability under varying climatic conditions.

Beyond these core areas, DOTP is also found in flexible packaging, synthetic leather, adhesives, sealants, and even some consumer goods where its safety profile is particularly advantageous. The compound’s compatibility with PVC and its ability to impart superior properties without the drawbacks of traditional phthalates make it a versatile and indispensable additive.
