Description

2-Oxepanone, Polymer With 1,6-Hexanediol CAS NO 36609-29-7 is a high-performance, biodegradable aliphatic polyester copolymer derived from caprolactone and hexanediol. This material is engineered to offer an exceptional balance of flexibility, toughness, and hydrolyzability, making it a critical component in advanced material formulations. It is primarily sought after by manufacturers in the medical device, controlled-release pharmaceutical, and specialty adhesive & coating industries seeking to enhance product performance with environmentally considerate materials.

Application

• Biodegradable Medical Implants: Used as a key polymer matrix for resorbable sutures, bone fixation devices, and soft tissue scaffolds due to its predictable degradation profile and biocompatibility.
• Controlled Drug Delivery Systems: Serves as a carrier polymer in microspheres, nanoparticles, and implantable rods for the sustained release of active pharmaceutical ingredients (APIs).
• Specialty Adhesives and Sealants: Imparts flexibility and adhesion in high-performance, moisture-curing polyurethane-based systems.
• Engineered Thermoplastic Elastomers (TPEs): Acts as a soft segment modifier to improve low-temperature flexibility and impact resistance in copolymer blends.
• Biodegradable Mulch Films and Agricultural Coatings: Utilized in formulations designed to degrade in soil, reducing plastic waste in farming applications.
• Toner Resin Additive: Enhances the low-temperature fusing properties and gloss of electrophotographic toners.

Quality Control

Every batch of our 2-Oxepanone, Polymer With 1,6-Hexanediol is manufactured under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) that detail critical parameters including monomer ratio, molecular weight distribution, intrinsic viscosity, and residual monomer content. Our quality protocols are designed to meet the stringent requirements of GMP for pharmaceutical applications and relevant ISO standards for industrial grades, ensuring batch-to-batch consistency and reliability.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep the container tightly sealed under dry, inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and potential hydrolysis. Keep away from strong alkalis and incompatible organic solvents.
