Description

1,2-Benzenedicarboxylic Acid, Di-C6-10-Alkyl Esters is a high-performance, high-molecular-weight phthalate plasticizer derived from mixed C6 to C10 linear alcohols. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior flexibility, durability, and low-temperature performance. It is a critical raw material for manufacturers in the polymer and plastics industries seeking to enhance the properties of their finished products. Its balanced characteristics make it a preferred choice for applications requiring a combination of processability and long-term stability.

Application

• Primary Plasticizer for PVC: Used extensively in flexible polyvinyl chloride (PVC) formulations for cables, wires, flooring, synthetic leather, and coated fabrics.
• Polymer Modification Agent: Imparts flexibility and workability to other polymers such as polyurethanes, nitrocellulose, and certain synthetic rubbers.
• Adhesive and Sealant Formulations: Acts as a non-volatile processing aid and flexibilizer in industrial adhesives, caulks, and sealants.
• Printing Inks and Coatings: Serves as a pigment grinding aid and resin modifier to improve flow, gloss, and adhesion in various coating systems.
• Gasket and Hose Production: Provides the necessary flexibility and compression set resistance in elastomeric components for automotive and industrial use.
• Consumer Goods Manufacturing: Used in the production of flexible toys, mats, and other molded or extruded plastic goods.
