Description

Ditridecyl Phthalate is a high-molecular-weight phthalate ester plasticizer known for its excellent permanence and low volatility. This compound is valued for its ability to impart superior flexibility, durability, and resistance to extraction in demanding polymer applications. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for formulating high-performance products requiring long-term stability.

Application

• Primary plasticizer for polyvinyl chloride (PVC), imparting excellent flexibility and low-temperature performance.
• Key component in the formulation of high-quality, durable vinyl flooring and wall coverings.
• Essential for manufacturing flexible PVC cables, wires, and hoses requiring long-term plasticizer retention.
• Used in synthetic leather, automotive interiors, and coated fabrics to enhance softness and longevity.
• Plasticizer for adhesives, sealants, and caulks to improve workability and final film properties.
• Functional additive in specialty polymer blends and elastomers to modify processing and physical characteristics.
