Description

2-Oxepanone, Polymer With 1,4-Butanediol And 1,1'-Methylenebis[4-Isocyanatocyclohexane] is a high-performance polycaprolactone-based polyurethane prepolymer. This specialized material matters for its unique combination of hydrolytic stability, flexibility, and biocompatibility derived from its segmented polymer structure. It is primarily needed by manufacturers in the medical device, specialty adhesive, and advanced elastomer industries seeking durable and customizable polymer matrices.

Application

• Medical Device Coatings: Used as a key component in biocompatible, flexible coatings for catheters, guidewires, and other implantable or insertable devices.
• Specialty Adhesives & Sealants: Serves as a base polymer for high-performance, moisture-curing adhesives requiring excellent adhesion and elasticity.
• Advanced Thermoplastic Polyurethanes (TPU): Acts as a prepolymer or soft segment in the synthesis of TPUs for automotive, industrial, and consumer goods.
• Biodegradable & Bioresorbable Materials: Utilized in research and development of controlled-release drug delivery systems and temporary medical scaffolds.
• High-Performance Elastomers: Formulated into castable elastomers for gaskets, rollers, and industrial parts demanding resilience and chemical resistance.
• Composite Matrix Resin: Functions as a toughening agent or flexible matrix component in advanced composite materials.

Quality Control

Our production of 2-Oxepanone, Polymer With 1,4-Butanediol And 1,1'-Methylenebis[4-Isocyanatocyclohexane] adheres to a strict quality management system. Each batch undergoes rigorous analytical testing, including determination of NCO content, viscosity, and residual monomer levels, to ensure consistency and performance. Certificates of Analysis (COA) documenting key specifications are available upon request. We support compliance with relevant regulatory frameworks for industrial and specialized applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic) and may react with atmospheric moisture; ensure containers are sealed under dry conditions (e.g., under nitrogen blanket) after opening to prevent premature curing or property changes. Keep away from strong acids, bases, and oxidizing agents.
