Description

Isooctyl Nonyl Phthalate is a specialized high-molecular-weight phthalate plasticizer known for its excellent performance characteristics. This compound is valued for its ability to impart superior flexibility, low volatility, and enhanced durability to polymer matrices, particularly PVC. It is a critical material for manufacturers seeking reliable plasticizers for demanding applications that require long-term stability and resistance to extraction. Key industries that utilize this product include wire and cable insulation, automotive interiors, and specialty polymer compounding.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds in wire and cable jacketing.
• Key component in the formulation of automotive interior parts such as dashboards, door panels, and seals.
• Used in the production of synthetic leather, flooring materials, and coated fabrics.
• Plasticizer for adhesives, sealants, and polymer gels requiring low migration.
• Imparts flexibility and processability to specialty polymers and elastomers.
• Applicable in the manufacture of gaskets, hoses, and other industrial rubber goods.

Quality Control

Our Isooctyl Nonyl Phthalate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical parameters. We provide full traceability and Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. 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.
