Description

2-Oxepanone, Polymer With 1,4-Butanediol, 1,3-Diisocyanatomethylbenzene And 2,2-Oxybisethanol is a specialized polyurethane prepolymer or resin derived from ε-caprolactone (2-oxepanone), butanediol, a diisocyanate, and diethylene glycol. This compound matters for its ability to impart enhanced flexibility, hydrolytic stability, and biocompatibility to final polymer formulations. It is primarily needed by manufacturers in the medical device, specialty adhesive, coating, and high-performance elastomer industries seeking advanced material properties.

Application

• Medical-grade Polyurethanes: Used as a key component in the synthesis of biocompatible polymers for catheters, wound dressings, and soft tissue implants.
• High-Performance Coatings: Serves as a resin base for durable, flexible, and chemical-resistant coatings for industrial equipment and automotive parts.
• Specialty Adhesives & Sealants: Imparts toughness and adhesion in formulations requiring resistance to moisture and environmental stress.
• Elastomer Manufacturing: Acts as a prepolymer for producing thermoplastic polyurethane (TPU) elastomers with excellent mechanical properties.
• Biodegradable Polymer Blends: Utilized in research and development of controlled-release matrices and biodegradable materials due to the caprolactone segments.
• Textile & Fiber Coatings: Applied to create water-resistant yet breathable coatings on technical textiles.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized for critical parameters including NCO content, viscosity, and residual monomer levels. Certificates of Analysis (COA) detailing these specifications are available upon request. Production can adhere to ISO 9001 quality management principles, and relevant biocompatibility testing data can be provided for medical-grade inquiries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is moisture-sensitive (hygroscopic) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent premature reaction and degradation. Keep away from strong acids, bases, and oxidizing agents.
