Description

Nonyl Undecyl Phthalate is a high-molecular-weight phthalate ester plasticizer, known for its excellent performance in demanding polymer applications. Its primary value lies in providing superior permanence, low volatility, and enhanced flexibility to PVC and other synthetic resins, even at elevated temperatures. This makes it an essential component for manufacturers in the wire and cable, automotive, and specialty film industries seeking durable and reliable plasticized compounds.

Application

• Primary plasticizer for high-temperature PVC wire and cable insulation and jacketing.
• Key component in automotive interior parts, such as dashboards and door panels, requiring low fogging and good cold flexibility.
• Formulation of durable, flexible PVC films and sheets for industrial and construction applications.
• Production of synthetic leather and coated fabrics where long-term flexibility and resistance to extraction are critical.
• Plasticizer for specialty adhesives, sealants, and caulks requiring low migration and good aging properties.
• Modifier for nitrocellulose and other specialty polymer systems to improve workability and film properties.

Quality Control

Our Nonyl Undecyl Phthalate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical physical-chemical parameters. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong alkalis and incompatible materials. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
