Description

Isononyl Undecyl Phthalate is a high-performance, branched-chain phthalate plasticizer. This compound is engineered to provide superior permanence, low volatility, and excellent compatibility with a wide range of polymers. It is a critical material for formulators seeking durable and flexible end-products in demanding industrial applications. Key users include manufacturers in the plastics, coatings, and specialty chemical sectors.

Application

• Primary plasticizer for PVC (polyvinyl chloride) and other vinyl polymers, imparting flexibility and low-temperature performance.
• Formulation of flexible PVC products such as cables, wires, hoses, and industrial sheeting.
• Production of synthetic leathers, coated fabrics, and tarpaulins requiring long-term durability.
• Component in adhesives and sealants to enhance flexibility and adhesion.
• Use in polymer dispersions and specialty coatings for improved film formation and elasticity.
• Plasticizer for printing inks and color concentrates to optimize rheology and substrate adhesion.
• Formulation of gaskets, profiles, and other extruded or molded rubber and plastic articles.

Quality Control

Our Isononyl Undecyl Phthalate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against rigorous internal specifications for purity, color, acidity, and key physical properties. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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 prevent moisture absorption and contamination.
