Description

Isodecyl Isononyl Phthalate CAS NO 85168-75-8 is a high-molecular-weight phthalate ester plasticizer, valued for its excellent permanence and low volatility. This compound is engineered to provide superior performance in demanding polymer applications where durability and flexibility are critical. It is primarily required by manufacturers in the plastics, coatings, and specialty chemical industries seeking a reliable and efficient plasticizer.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds, including wire & cable insulation, flooring, and automotive interiors.
• Key component in the formulation of synthetic rubbers and elastomers to enhance processability and end-product flexibility.
• Used in the production of adhesives, sealants, and caulks to improve adhesion and elongation properties.
• Plasticizer for coating resins to achieve desired film formation and durability.
• Functional fluid in specialty lubricants and greases.
• Intermediate in the synthesis of other specialty esters and chemical products.

Quality Control

Our Isodecyl Isononyl Phthalate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, and physical properties. Certificates of Analysis (COA) documenting batch-specific results 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 strong alkalis and 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 minimize moisture absorption and contamination.
