Description

1,2-Benzenedicarboxylic Acid, Di-C7-9-Branched And Linear Alkyl Esters is a high-performance phthalate-based plasticizer, specifically a mixture of diisononyl and diisodecyl phthalate isomers. This compound is valued for its excellent compatibility with PVC and other polymers, providing enhanced flexibility, durability, and low-temperature performance to finished products. It is a critical raw material for manufacturers in the plastics, coatings, and adhesive industries seeking reliable and efficient plasticizing solutions.

Application

• Primary Plasticizer for PVC: Used in the production of flexible PVC products such as cables, wires, hoses, flooring, and synthetic leather.
• Polymer Modification: Imparts flexibility and workability to various resins and elastomers beyond PVC.
• Adhesives and Sealants: Acts as a processing aid and flexibilizer in formulations to improve adhesion and elasticity.
• Coatings and Inks: Serves as a coalescing agent and plasticizer to enhance film formation, flexibility, and gloss.
• Rubber Compounding: Used as a softener and processing aid in certain rubber formulations.
• Industrial and Consumer Goods: Found in a wide range of products from automotive parts to footwear and stationery items.
