Description

Ditridecyl Phthalate (DTDP) is a high-molecular-weight diester plasticizer derived from phthalic anhydride and a mixture of tridecyl alcohols. This compound is valued for its excellent permanence, low volatility, and superior performance in demanding polymer applications. It is primarily used by formulators in the plastics, rubber, and specialty coatings industries seeking to enhance the flexibility, durability, and processing characteristics of their products.

Application

• Primary Plasticizer for PVC: Imparts excellent low-temperature flexibility and long-term permanence in high-performance PVC applications such as wire and cable insulation, automotive interiors, and coated fabrics.
• Specialty Polymer Additive: Used in synthetic rubbers, polyurethanes, and certain elastomers to improve processability and final product resilience.
• High-Temperature Lubricants and Greases: Serves as a synthetic base fluid or additive due to its thermal stability and viscosity properties.
• Adhesive and Sealant Formulations: Acts as a non-volatile plasticizer to maintain flexibility and adhesion over time.
• Printing Inks and Coatings: Provides pigment wetting and flow control in specialty coating systems requiring low migration.
