Description

1,2-Benzenedicarboxylic Acid, Benzyl C7-9-Branched And Linear Alkyl Esters is a high-performance, high-molecular-weight plasticizer belonging to the class of benzyl esters of mixed phthalic acids. This compound is engineered to provide superior permanence, low volatility, and excellent compatibility with a wide range of polymers, making it a critical component for demanding applications. It is primarily sought after by formulators in the plastics, coatings, and specialty chemical industries who require enhanced product durability and performance under challenging conditions.

Application

• Primary Plasticizer for PVC and other Polymers: Imparts excellent flexibility, low-temperature performance, and resistance to extraction in vinyl compounds, wire & cable insulation, and synthetic leather.
• High-Performance Adhesives and Sealants: Enhances adhesion, flexibility, and longevity in construction and industrial sealant formulations.
• Specialty Coatings and Inks: Used as a polymeric plasticizer to improve film formation, flexibility, and weathering resistance in coatings for automotive, industrial, and marine applications.
• Synthetic Rubber Compounding: Acts as a processing aid and plasticizer to improve the workability and elastic properties of various elastomers.
• Caulks and Putties: Provides lasting flexibility and prevents cracking or hardening over time in building and automotive sealants.
• Gasket and Hose Formulations: Contributes to the durability and compression set resistance of rubber-based gaskets and hoses.
