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.

 

Dioctyl terephthalate (DOTP) is an excellent main plasticizer for polyvinyl chloride (PVC) plastics.

 

Introduction

1.DOTP is a sort of high-performance primary plasticizer with good electrothermal properties. Its volume resistivity is ten-twenty times of DOP’s. Good plasticating effect and low volatility on cable materials makes it be widely used on the heat-resisting, high insulation product. It is the ideal plasticizer for the production of 70 degrees C. cable material and other volatility-resist PVC products.
2.Meanwhile it has favourable cold-resistance, heat-resistance, extraction-resistance performace, with low volatility and high plasticizing efficiency. In its downstream products, good durability, soap water resistance and softness in low temp. was been found. It is suitable for the plasticizer of PVC resins, such as high-insulation PVC cables.
3.This product can be mixed with DOP at free percentage.
4.This product can reduce viscosity and increase preserve life in the application of plasticized paste.

Application Guide:
Widely used in cable materials, insulating wires, high-grade paint, coating, PVC gloves, artificial leather, etc.
