Industrial Grade Dioctyl Terephthalate / DOTP Plasticizer CAS 6422-86-2

Dioctyl Terephthalate/ DOTP Industrial Grade CAS 6422-86-2

Description:
Dioctyl Terephthalate (DOTP) is a clear, colorless liquid that belongs to the class of phthalate plasticizers. It is derived from terephthalic acid and 2-ethylhexanol. DOTP is known for its excellent flexibility, high thermal stability, and low volatility.

Specification:
The specifications of Dioctyl Terephthalate can vary depending on the specific grade and application. Here are some general specifications:

• Chemical formula: C24H38O4
• Molecular weight: 390.56 g/mol
• Appearance: Clear, colorless liquid
• Density: Approximately 0.982 g/cm³
• Boiling point: Approximately 386 °C
• Flashpoint: Approximately 192 °C
• Solubility: Insoluble in water, but miscible with most organic solvents
• Purity: Typically, not less than 99% or higher (depending on the grade)

Application:

1. Plasticizer: Dioctyl Terephthalate is primarily used as a plasticizer in the production of flexible PVC (polyvinyl chloride) products. It imparts flexibility, durability, and softness to PVC-based materials. Common applications include:

   • Wire and cable insulation: DOTP is used to manufacture flexible PVC insulation for wires and cables, providing electrical insulation properties along with excellent flexibility.
   • Floorings and wall coverings: It is used in the production of PVC floorings, wall coverings, and synthetic leather, where flexibility, abrasion resistance, and durability are desired.
   • Automotive parts: DOTP is used in the manufacturing of automotive interior parts, such as dashboards, door panels, and upholstery, to enhance flexibility, heat resistance, and longevity.
   • Medical devices: It can be used in medical devices and equipment, where flexibility and resistance to sterilization methods are required.

2. Other applications: Apart from being a plasticizer, DOTP has some additional applications, including:

   • Adhesives: DOTP can be used as a component in adhesives formulations, providing flexibility and adhesive properties.
   • Coatings: It can be incorporated into coatings to improve flexibility and adhesion.
   • Printing inks: DOTP is used in the formulation of printing inks, providing good solvency and enhancing printability.

Features:

1. Excellent flexibility: DOTP is known for its outstanding flexibility, which makes it suitable for a wide range of applications that require flexible PVC materials.

2. High thermal stability: Dioctyl Terephthalate exhibits high thermal stability, allowing it to withstand high-temperature processing and applications without significant degradation.

3. Low volatility: DOTP has low volatility, meaning it has minimal tendency to evaporate at normal temperatures. This characteristic contributes to the long-term stability and durability of the plasticized products.

4. Good electrical properties: It imparts desirable electrical insulation properties to PVC-based materials, making it suitable for applications in the electrical and electronics industry.

5. Low toxicity: DOTP is considered to have low toxicity and is often chosen as a replacement for certain phthalate plasticizers with potential health concerns, such as DEHP (diethylhexyl phthalate). However, it is essential to follow recommended handling and safety guidelines.
