Description

Hexanedioic Acid, Polymer With 1,3-Butanediol, 2-Ethylhexyl Ester is a high-performance polymeric plasticizer derived from adipic acid. This compound is engineered to provide superior flexibility, low-temperature performance, and durability to polymer matrices, making it a critical additive for demanding applications. It is essential for manufacturers in the plastics, coatings, and adhesives industries seeking to enhance product longevity and performance under varied environmental conditions.

Application

• Primary plasticizer for PVC (Polyvinyl Chloride) and other polar polymers, imparting excellent flexibility and elongation.
• Key component in the formulation of high-performance sealants and caulks requiring long-term weatherability and low migration.
• Modifier for industrial and automotive coatings to improve film flexibility, adhesion, and resistance to cracking.
• Functional additive in adhesives and pressure-sensitive adhesives (PSAs) to adjust tack and peel properties.
• Plasticizer for specialty wire and cable insulation compounds demanding good electrical properties and thermal stability.
• Used in the production of synthetic leathers and coated fabrics to achieve a soft, leather-like feel.
• Additive in printing inks and overprint varnishes to enhance gloss and flexibility on various substrates.

Quality Control

Our production of Hexanedioic Acid, Polymer With 1,3-Butanediol, 2-Ethylhexyl Ester adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistency in key parameters such as acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong alkalis and incompatible organic solvents.
