Description

Hexanedioic Acid, Polymer With 1,3-Butanediol And 1,6-Hexanediol is a specialized aliphatic polyester polyol, synthesized from adipic acid and a blend of diols. This engineered polymer is valued for its ability to impart flexibility, hydrolytic stability, and specific mechanical properties to final formulations. It is a critical raw material for manufacturers in the polyurethane, coatings, adhesives, and specialty elastomers industries seeking consistent performance and tailored polymer characteristics.

Application

• Polyurethane Elastomers & Thermoplastic Polyurethanes (TPU): Serves as a key soft segment component to produce flexible, durable, and abrasion-resistant materials for automotive parts, industrial wheels, and cable sheathing.
• Coatings & Adhesives: Used in the formulation of high-performance polyurethane coatings, sealants, and adhesives, providing excellent adhesion, flexibility, and chemical resistance.
• Resins for Composite Materials: Acts as a reactive intermediate in the production of unsaturated polyester resins or other composite matrices, enhancing toughness and impact resistance.
• Specialty Plasticizers & Modifiers: Employed as a polymeric plasticizer or modifier to improve the low-temperature flexibility and processing of PVC and other polymers.
• Biomedical & Controlled Release Systems: Potential use in the synthesis of biodegradable polymers for medical devices or drug delivery applications due to its aliphatic ester backbone.

Quality Control

Our production of this polyester polyol adheres to stringent quality management protocols. Each batch is characterized by key parameters including hydroxyl number (OH#), acid value, viscosity, and water content to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global standards for industrial chemical manufacturing.

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). To prevent moisture uptake and potential property degradation, containers must be kept sealed when not in use. Under these conditions, the product remains stable for extended periods.
