Description

1,2-Benzenedicarboxylic Acid Di-C9-11-Branched Alkyl Esters C10-Rich is a high-performance, high-molecular-weight phthalate plasticizer, specifically engineered with a C10-rich branched alkyl chain profile. This formulation is critical for providing superior low-temperature flexibility, excellent permanence, and enhanced processability in demanding polymer applications. It is an essential raw material for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable and consistent performance in their end products.

Application

• Primary Plasticizer for PVC: Imparts excellent flexibility, durability, and low-temperature performance to PVC compounds used in cables, hoses, flooring, and synthetic leather.
• Specialty Polymer Modifier: Enhances the workability and physical properties of various polymers, including polyurethanes, nitrocellulose, and synthetic rubbers.
• Adhesive and Sealant Formulations: Acts as a processing aid and flexibilizer, improving adhesion, cohesion, and application properties.
• Industrial and Protective Coatings: Used in plastisols and organosols to provide flexibility, impact resistance, and weatherability to coated fabrics and metal coatings.
• Printing Inks and Pigment Dispersions: Serves as a high-boiling-point solvent and carrier, aiding in pigment wetting and providing stable viscosity.
• Lubricant and Functional Fluid Additive: Employed as a base or additive in synthetic lubricants and greases for its thermal stability and viscosity properties.

Quality Control

Our 1,2-Benzenedicarboxylic Acid Di-C9-11-Branched Alkyl Esters C10-Rich is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for color, acidity, ester content, and volatility. Certificates of Analysis (COA) documenting purity, physical properties, and compliance with relevant industry standards (such as REACH) are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from strong acids, strong oxidizers, and heat sources. As the product is an organic ester, prolonged exposure to high temperatures or open flame should be avoided.
