Description

Hexanedioic Acid, Polymer With 1,3-Butanediol, Diesters With C14-18 Fatty Acids is a high-performance polymeric ester, commonly known as a polyol ester-based polymeric plasticizer. This specialized chemical offers a unique balance of compatibility, permanence, and low-temperature flexibility, making it a superior alternative to traditional monomeric plasticizers. It is engineered for demanding applications where long-term durability and performance stability are critical. Key industries that rely on this advanced polymer include high-end polymer manufacturing, specialty adhesives, and advanced coating systems.

Application

• Primary Plasticizer for PVC and other Polymers: Imparts excellent flexibility, low volatility, and resistance to extraction in vinyl compounds for wires, cables, films, and sheets.
• High-Performance Adhesives and Sealants: Acts as a permanent, non-migrating plasticizer to enhance flexibility and adhesion in polyurethane, polysulfide, and other elastomeric sealant formulations.
• Specialty Coating Resins: Used in polyurethane and nitrocellulose lacquers to improve film flexibility, gloss, and durability.
• Synthetic Leather and Artificial Leather Production: Provides a soft, leather-like hand feel and excellent aging properties in PU and PVC-based synthetic leathers.
• Gasket and O-Ring Compounds: Enhances the low-temperature performance and compression set resistance of nitrile rubber and other elastomers.
• Printing Ink Vehicles: Serves as a resin modifier in flexographic and gravure inks to improve pigment wetting and film formation.

Quality Control

Our production of Hexanedioic Acid, Polymer With 1,3-Butanediol, Diesters With C14-18 Fatty Acids adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) documenting these parameters 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, well-ventilated area away from incompatible materials such as strong alkalis and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to minimize moisture absorption and contamination.
