Description

Poly(1 6-Hexamethylene Adipate) is a high-performance, linear aliphatic polyester derived from hexamethylene diol and adipic acid. This polymer is valued for its excellent flexibility, hydrolytic stability, and compatibility in demanding formulations. It serves as a critical intermediate and performance additive for manufacturers in the polyurethane, coatings, and specialty plastics industries seeking to enhance material properties.

Application

• Polyurethane Elastomers & Thermoplastics (TPU): Used as a soft segment or chain extender to impart flexibility, resilience, and low-temperature performance to polyurethane systems.
• High-Performance Coatings & Adhesives: Acts as a key polymeric diol in the synthesis of polyester polyols for durable, flexible, and chemical-resistant coatings, sealants, and adhesives.
• Biodegradable & Bio-based Polymers: Serves as a building block for developing sustainable, aliphatic polyesters with targeted degradation profiles.
• Plasticizers & Modifiers: Employed as a polymeric plasticizer to improve the low-temperature flexibility and processing of PVC and other rigid polymers.
• Specialty Resins & Composites: Incorporated into resin formulations to enhance toughness, impact resistance, and adhesion in composite materials.
• Fiber & Film Production: Utilized in the production of specialty fibers and films requiring a balance of strength and elasticity.

Quality Control

Our Poly(1 6-Hexamethylene Adipate) is manufactured under a strict quality management system. Each batch is characterized for critical parameters including acid value, hydroxyl value, molecular weight distribution, and moisture content to ensure consistent performance in your application. Certificates of Analysis (COA) documenting these specifications are provided with every shipment.

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) to prevent moisture absorption and potential hydrolysis.
