Description

Hexanedioic Acid, Polymer With Butanedioic Acid, 1,4-Butanediol And 1,2-Ethanediol CAS NO 70776-91-9 is a high-performance, aliphatic polyester polyol copolymer derived from adipic acid, succinic acid, and a blend of glycols. This engineered polymer offers a unique balance of flexibility, hydrolytic stability, and reactivity, making it a critical intermediate for demanding industrial formulations. It is essential for manufacturers seeking to enhance the durability and performance characteristics of polyurethane systems, coatings, and specialty elastomers.

Application

• Polyurethane Elastomers & Castables: Serves as a key polyol component for producing high-resilience, abrasion-resistant, and hydrolysis-stable elastomers used in industrial wheels, rollers, and seals.
• Coatings & Adhesives: Imparts excellent flexibility, adhesion, and chemical resistance to polyurethane coatings for textiles, plastics, and metal substrates, as well as high-performance adhesives and sealants.
• Thermoplastic Polyurethane (TPU): Used in the synthesis of TPUs for applications requiring a fine-tuned balance of hardness, low-temperature flexibility, and processing stability.
• Foam Systems: Can be utilized in the formulation of specialized microcellular foams and flexible foam systems where enhanced mechanical properties are required.
• Resin Modification: Acts as a polymeric plasticizer or modifier for other resin systems to improve impact resistance and flexibility.
• Industrial Fiber & Film: Employed in the production of specialty fibers and films that demand toughness and environmental stability.

Quality Control

Our production of this copolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are provided with each shipment 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). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
