Description

2-Oxepanone, Polymer With 1,2-Ethanediol is a high-purity polymeric material derived from the reaction of ε-caprolactone (2-oxepanone) with ethylene glycol (1,2-ethanediol). This compound is valued for its excellent biodegradability, biocompatibility, and tunable physical properties, making it a critical intermediate for advanced material synthesis. It is primarily sought by manufacturers in the biomedical, pharmaceutical, and specialty polymer industries for applications ranging from drug delivery systems to environmentally friendly plastics.

Application

• Biodegradable Polymers: Serves as a key monomer for synthesizing poly(ε-caprolactone) (PCL) and its copolymers, used in compostable packaging and agricultural films.
• Biomedical Engineering: Essential for creating bioresorbable sutures, tissue engineering scaffolds, and controlled-release matrices for pharmaceuticals.
• Drug Delivery Systems: Utilized in the formulation of microspheres, nanoparticles, and implants for sustained and targeted therapeutic release.
• Adhesives & Coatings: Acts as a modifier in polyurethane systems and specialty coatings to enhance flexibility, adhesion, and degradation profiles.
• 3D Printing Filaments: Incorporated into resin formulations for stereolithography (SLA) and fused deposition modeling (FDM) to produce biodegradable prototypes and parts.
• Cosmetic & Personal Care: Used in the synthesis of emulsifiers and delivery vehicles for active ingredients in creams and lotions.

Quality Control

Our production of 2-Oxepanone, Polymer With 1,2-Ethanediol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including molecular weight distribution (PDI), monomer conversion rate, and residual solvent content to ensure consistency and performance. Certificates of Analysis (COA) documenting purity, composition, and physical properties are available for every shipment. We support compliance with relevant frameworks for biomedical and industrial applications.

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 material is hygroscopic (moisture-sensitive). To prevent degradation and clumping, the container must be kept tightly sealed when not in use and consideration should be given to storage under an inert atmosphere for long-term preservation.
