Description

Hexanedioic Acid, Polymer With 1,4-Butanediol And 1,1-Methylenebis4-Isocyanatocyclohexane is a high-performance polyurethane prepolymer or polyurethane elastomer derived from aliphatic diisocyanates. This material matters for its excellent mechanical properties, hydrolytic stability, and resistance to yellowing, making it superior to aromatic polyurethanes in demanding environments. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialty films, fibers, and medical device components where durability and clarity are critical.

Application

• High-Performance Coatings: Used in formulations for automotive clear coats, industrial maintenance paints, and wood finishes requiring excellent UV stability and gloss retention.
• Elastomers and Castables: Serves as a key component in the production of durable rollers, wheels, gaskets, and seals that demand high tensile strength and abrasion resistance.
• Adhesives and Sealants: Provides strong, flexible bonds in construction, automotive assembly, and aerospace applications, often where resistance to moisture and chemicals is essential.
• Medical and Biocompatible Devices: Utilized in the manufacture of components for medical tubing, catheter balloons, and wound care dressings due to its potential biocompatibility and stability.
• Specialty Films and Fibers: Acts as a raw material for creating transparent, tear-resistant films for laminates and high-tenacity fibers for technical textiles.
• Composite Binders: Functions as a matrix resin or binder in fiber-reinforced composites for lightweight automotive and sporting goods parts.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch undergoes rigorous testing for key parameters such as NCO content, viscosity, and molecular weight distribution to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This product 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 premature polymerization or gelation.
