Description

2-Oxepanone, Polymer With 1,6-Diisocyanatohexane And 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is a specialized polycaprolactone-based polyurethane prepolymer. This compound matters for its unique combination of hydrolyzable ester linkages and robust urethane segments, offering a balance of mechanical strength and controlled degradation profiles. It is primarily needed by manufacturers in the biomedical, adhesive, and specialty coating industries seeking advanced, tunable polymer materials.

Application

• Biomedical Implants & Devices: As a key component in bioresorbable scaffolds, sutures, and drug delivery matrices due to its predictable degradation kinetics.
• Advanced Adhesives & Sealants: For formulating high-performance, flexible adhesives with excellent adhesion to diverse substrates.
• Specialty Coatings: Used in the development of durable, yet degradable, protective coatings for medical or industrial applications.
• Tissue Engineering: Serves as a base material for creating 3D-printed or molded scaffolds that support cell growth and tissue regeneration.
• Elastomer Modification: Acts as a modifier to enhance the toughness, flexibility, and processing characteristics of thermoplastic polyurethanes (TPUs).
• Controlled-Release Systems: Utilized in the encapsulation of agrochemicals or pharmaceuticals for sustained release.

Quality Control

Our production of this advanced polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance. Key parameters such as molecular weight distribution, isocyanate (NCO) content, and residual monomer levels are strictly monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and premature reaction.
