Description

Hexanedioic acid polymer with 1,4-butanediol, 1,6-diisocyanato hexane, dimethyl carbonate, 1,2-ethanediol, 2-ethyl-2-(hydroxy methyl)-1,3-propanediol, 1,6-hexanediol, 3-hydroxy-2-(hydroxy methyl)-2-methylpropanoic acid, 2-oxepanone and 2,2'-oxybis[ethanol] is a specialized, multi-component polyurethane or polyester-polyurethane copolymer designed for high-performance applications. This engineered polymer offers a unique balance of properties derived from its complex monomer composition, including flexibility, chemical resistance, and durability. It is essential for formulators and manufacturers in sectors requiring advanced material performance, such as coatings, adhesives, and specialty elastomers.

Application

• High-Performance Coatings: Used as a resin component in industrial, automotive, and protective coatings for enhanced weatherability, gloss, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a key polymer backbone in structural adhesives, laminating agents, and flexible sealants requiring strong bonding and elasticity.
• Specialty Elastomers and Urethane Rubbers: A critical raw material for producing castable, thermoplastic, or millable polyurethane elastomers with tailored hardness and tensile strength.
• Biomedical and Controlled-Release Materials: Potential use in biocompatible matrices for drug delivery systems or medical device coatings due to its tunable degradation profile.
• Composite Materials: Acts as a matrix resin or compatibilizer in fiber-reinforced plastics and polymer blends to improve impact strength and interfacial adhesion.
• Flexible Foams and Cushioning: Can be formulated into flexible polyurethane foams for specialized cushioning applications requiring specific resilience and density.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters. Each lot is characterized for key properties such as hydroxyl value, isocyanate content, viscosity, and molecular weight distribution. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every 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 material is moisture-sensitive; keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizers and heat sources.
