Description

Poly(2-Hydroxyacetic Acid) is a high-purity synthetic polymer derived from glycolic acid, known for its excellent biodegradability and biocompatibility. This material is crucial for industries requiring reliable, high-performance bioresorbable components with predictable degradation profiles. It is primarily sought after by manufacturers in the medical device, pharmaceutical, and specialty chemical sectors for advanced applications.

Application

• Medical Sutures and Implants: As a key component in bioresorbable surgical sutures, screws, pins, and meshes that safely degrade in the body.
• Controlled Drug Delivery Systems: Used in the formulation of microspheres, nanoparticles, and implants for sustained release of pharmaceutical actives.
• Tissue Engineering Scaffolds: Provides a structural matrix for cell growth and tissue regeneration in advanced biomedical applications.
• Specialty Packaging: For high-value, biodegradable packaging solutions in niche markets.
• Cosmetic Formulations: As a film-forming agent or carrier for active ingredients in premium skincare products.
• Industrial Absorbents & Specialty Fibers: In the production of non-woven fabrics and absorbent materials with specific end-of-life characteristics.

Quality Control

Our Poly(2-Hydroxyacetic Acid) is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for molecular weight, polydispersity, residual monomer content, and intrinsic viscosity. Certificates of Analysis (COA) documenting compliance with relevant standards are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept sealed to prevent moisture absorption, which can affect polymer properties. Recommended long-term storage at controlled room temperature (15-25°C).
