Description

2-Oxepanone, Polymer With 1,6-Diisocyanatohexane And 1,6-Hexanediol is a high-performance, segmented polyurethane copolymer synthesized from ε-caprolactone, hexamethylene diisocyanate (HDI), and 1,6-hexanediol. This engineered polymer is valued for its excellent mechanical properties, hydrolytic stability, and biocompatibility, making it a critical material for advanced manufacturing. It is primarily sought by manufacturers in the medical device, specialty adhesive, and high-performance elastomer industries seeking reliable, consistent raw materials.

Application

• Medical Device Components: Used in the fabrication of biodegradable implants, drug delivery systems, and surgical meshes due to its biocompatibility and controlled degradation profile.
• High-Performance Adhesives & Sealants: Serves as a key polyol component in formulating moisture-curing and two-component polyurethane adhesives with superior flexibility and chemical resistance.
• Specialty Elastomers and Coatings: Employed to produce thermoplastic polyurethanes (TPUs) for applications requiring a balance of toughness, elasticity, and weatherability.
• Tissue Engineering Scaffolds: Acts as a base polymer for creating porous, bioresorbable scaffolds that support cell growth and tissue regeneration.
• Controlled-Release Matrices: Utilized in pharmaceutical and agricultural formulations to encapsulate active ingredients for sustained release.
• Advanced Composite Materials: Incorporated as a toughening agent or matrix resin in composites for automotive and aerospace applications.

Quality Control

Our production of this segmented copolymer adheres to strict quality management systems to ensure batch-to-batch consistency for critical applications. Key parameters such as molecular weight distribution (PDI), residual monomer content, and thermal properties are rigorously monitored. Certificates of Analysis (COA) detailing specifications for each lot are available upon request, and production can be aligned with ISO 13485 standards for medical-grade material.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This polymer is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent hydrolysis of the ester linkages prior to processing.
