Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,3-Diisocyanatomethylbenzene And .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl) is a specialized polyurethane-polyether copolymer designed for high-performance applications. This engineered polymer offers a unique balance of flexibility, toughness, and chemical resistance derived from its segmented structure. It is essential for formulators and manufacturers in industries requiring durable, customizable elastomers and coatings.

Application

• High-Performance Elastomers: Used in the production of castable polyurethane elastomers for industrial rollers, seals, gaskets, and impact-absorbing components.
• Specialty Coatings and Adhesives: Serves as a key resin in formulating protective coatings, sealants, and adhesives that demand excellent weatherability and adhesion.
• Textile and Fiber Finishing: Employed as a durable, flexible coating or binder for technical textiles and synthetic fibers.
• Automotive Components: Utilized in under-the-hood parts, interior trim, and other components requiring oil and solvent resistance.
• Footwear and Sporting Goods: A base material for manufacturing durable soles, midsoles, and other flexible parts.
• Medical Device Components: Potential use in non-implantable medical device parts where biocompatibility and specific mechanical properties are needed (subject to grade and validation).

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl number, isocyanate content, viscosity, and molecular weight distribution to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing these specifications are provided and available upon request to support your quality assurance protocols.

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 premature reaction.
