Description

n-Octyl-n-Decyl Phthalate is a high-molecular-weight diester plasticizer, specifically a mixed C8-C10 linear alkyl phthalate. This compound is valued for its excellent permanence, low volatility, and superior performance in demanding polymer applications. It is a critical material for manufacturers requiring durable, flexible, and low-migration plasticized products across several key industries.

Application

• Primary plasticizer for Polyvinyl Chloride (PVC), imparting excellent flexibility and long-term durability.
• Key component in the production of high-performance wire and cable insulation and jacketing due to its low volatility and good electrical properties.
• Formulation of flexible calendered films and sheets for automotive interiors, flooring, and wall coverings.
• Manufacture of synthetic leather and coated fabrics, providing a soft, leather-like feel with good resistance to extraction.
• Used in adhesives, sealants, and caulks to improve flexibility and workability.
• Plasticizer for nitrocellulose and other specialty polymers in coatings and inks.
• Employed in gasket and seal formulations requiring resistance to migration and aging.

Quality Control

Our n-Octyl-n-Decyl Phthalate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance characteristics. A Certificate of Analysis (COA) documenting key parameters such as assay, color, acidity, and specific gravity is provided with each shipment to guarantee consistency and compliance with your formulation requirements.

Storage

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