Description

Hexanedioic Acid, Polymer With 1,9-Nonanediol is a high-performance, synthetic polyester polyol derived from adipic acid and a linear diol. This polymer is valued for its ability to impart flexibility, hydrolytic stability, and excellent mechanical properties to final formulations. It is primarily sought after by manufacturers in the polyurethane, coatings, adhesives, and specialty elastomers industries for creating durable and resilient products.

Application

• Polyurethane Elastomers: As a key soft segment component for producing flexible, abrasion-resistant, and hydrolysis-stable elastomers used in industrial wheels, seals, and gaskets.
• Coatings and Paints: Used in high-performance polyurethane coatings to enhance flexibility, adhesion, and chemical resistance for automotive, industrial, and marine applications.
• Adhesives and Sealants: Serves as a polymeric diol in moisture-cure and two-component polyurethane adhesives, providing strong bonding and durability.
• Thermoplastic Polyurethanes (TPU): A fundamental building block for manufacturing TPUs used in films, cables, hoses, and breathable textiles.
• Resins for Composites: Incorporated into resin systems to modify toughness and impact resistance in fiber-reinforced composites.
• Synthetic Leather and Artificial Leather: Used in the production of high-quality, flexible synthetic leather substrates with a soft hand feel.

Quality Control

Our production of Hexanedioic Acid, Polymer With 1,9-Nonanediol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, molecular weight distribution, and moisture content to ensure consistent performance in downstream applications. Comprehensive Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) when not in use to prevent moisture absorption and potential degradation.
