Description

1,2-Benzenedicarboxylic Acid, Nonyl Undecyl Ester, Branched And Linear is a high-molecular-weight diester plasticizer derived from phthalic acid. This compound is valued for its excellent compatibility with a wide range of polymers and its ability to impart flexibility and durability to finished products. It is primarily sought after by manufacturers in the plastics, polymer, and specialty chemical industries for formulating high-performance materials.

Application

• Primary plasticizer for flexible PVC (polyvinyl chloride) compounds in wire & cable insulation, flooring, and synthetic leather.
• Performance additive in adhesives and sealants to enhance flexibility and low-temperature properties.
• Functional fluid or processing aid in the production of elastomers and synthetic rubbers.
• Coalescing agent or plasticizer in specialty paints, coatings, and inks to improve film formation and durability.
• Lubricant and softening agent in the polymer processing industry.
• Intermediate for the synthesis of more complex specialty esters and chemical derivatives.

Quality Control

Our 1,2-Benzenedicarboxylic Acid, Nonyl Undecyl Ester is produced under a strict quality management system. Each batch is tested to ensure consistent purity, performance, and compliance with relevant industrial specifications. A comprehensive Certificate of Analysis (COA) detailing assay, physical properties, and impurity profiles is provided with every shipment to guarantee traceability and quality assurance for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve product integrity. Keep away from strong oxidizing agents and heat sources.
