Description

Poly(Sebacic Anhydride) is a high-purity, biodegradable polymer derived from sebacic acid, a naturally occurring dicarboxylic acid. This compound is valued for its controlled degradation profile and excellent biocompatibility, making it a critical material for advanced, environmentally conscious applications. It is primarily sought after by manufacturers in the biomedical, pharmaceutical, and specialty polymer industries for developing resorbable medical devices, drug delivery systems, and sustainable materials.

Application

• Biodegradable Polymers & Plastics: A key monomer for synthesizing poly(anhydride) copolymers used in environmentally friendly packaging and agricultural films.
• Controlled Drug Delivery Systems: Used to create bioerodible matrices for the sustained and localized release of therapeutic agents.
• Medical Devices & Implants: Serves as a fundamental building block for resorbable surgical sutures, bone fixation devices, and tissue engineering scaffolds.
• Microencapsulation: Employed in the encapsulation of sensitive actives, including vaccines, proteins, and fragrances, for protection and controlled release.
• Adhesives & Coatings: Utilized in the formulation of specialty biodegradable adhesives and protective coatings.
• Chemical Intermediate: Acts as a precursor for further chemical synthesis in pharmaceutical and fine chemical production.

Quality Control

Our Poly(Sebacic Anhydride) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for demanding applications. Each lot is characterized for critical parameters including molecular weight distribution, residual monomer content, and inherent viscosity. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and performance specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for the specific grade. This material is hygroscopic (moisture-sensitive) and must be handled under dry conditions or inert atmosphere to prevent hydrolysis and maintain stability.
