In the vast landscape of chemical additives, plasticizers are essential for tailoring the properties of polymers. Dioctyl Terephthalate (DOTP) has gained significant traction as a high-performance, eco-friendly plasticizer, particularly for PVC. Understanding its technical specifications and a wide range of applications is key for manufacturers seeking to optimize their material formulations. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive information and high-quality DOTP to meet these industry needs.

Key Technical Specifications of DOTP

The performance of any chemical additive is largely determined by its specific technical properties. DOTP boasts a profile that makes it highly desirable for numerous applications:

  • Appearance: Typically a colorless, transparent liquid, indicating purity and ease of handling.
  • Purity (Ester Content): Usually specified as ≥99.0% or ≥99.5%. High purity ensures consistent performance and minimal side reactions in formulations.
  • Density (at 20°C): Around 0.98-1.12 g/cm³. This property is important for volumetric calculations and material handling.
  • Acid Value: Typically ≤0.1 mg KOH/g or ≤0.02 mg KOH/g. A low acid value indicates minimal free acids, contributing to material stability and preventing corrosion.
  • Moisture Content: Usually ≤0.5% or even lower. Low moisture content is crucial for preventing issues during processing, such as hydrolysis or foam formation.
  • Flash Point: Generally ≥210°C. A high flash point signifies low flammability, enhancing safety during storage, handling, and processing.
  • Color (PT-Co Number): Specified as ≤200 or lower. A low color value is desirable for applications where the final product's color is critical.

These specifications collectively highlight DOTP's suitability for demanding applications where quality and consistency are paramount.

Diverse Applications of DOTP Plasticizer

DOTP's versatility stems from its excellent plasticizing capabilities, low volatility, and good resistance to migration. These properties make it a preferred choice across various industries:

  • PVC Products: DOTP is widely used in flexible PVC applications such as films, sheets, flooring, wall coverings, automotive interiors, and coated fabrics. It imparts the necessary flexibility and durability required for these products.
  • Wire and Cable Insulation: Its excellent electrical properties and thermal stability make it ideal for insulating electrical wires and cables.
  • Food Contact Applications: Due to its non-toxic and odorless nature, DOTP is approved for use in food packaging materials, meeting stringent safety standards.
  • Medical Devices: Its safety and inertness are crucial for flexible medical components like IV tubing, blood bags, and medical gloves.
  • Coatings and Adhesives: DOTP enhances the flexibility and weather resistance of various coating and adhesive formulations.
  • Toys: Its safety profile makes it a preferred plasticizer for the manufacturing of children's toys.
