Description

Poly(L-Lactic Acid) CAS NO 26811-96-1 is a high-purity, biodegradable polymer derived from renewable resources, representing a cornerstone of sustainable material science. Its primary value lies in its excellent biocompatibility and controlled degradation profile, making it indispensable for advanced medical and packaging applications. This material is essential for manufacturers in the biomedical, pharmaceutical, and eco-friendly packaging industries seeking reliable, high-performance biopolymers.

Application

• Medical Implants & Devices: Used in the manufacture of bioresorbable sutures, screws, plates, and scaffolds for tissue engineering due to its biocompatibility and predictable resorption rate.
• Controlled Drug Delivery Systems: Serves as a key excipient in microspheres, nanoparticles, and implants for the sustained and targeted release of pharmaceutical actives.
• Eco-Friendly Packaging: A primary material for producing compostable films, containers, and coatings, offering a sustainable alternative to conventional plastics.
• 3D Printing (Additive Manufacturing): Utilized as a filament in Fused Deposition Modeling (FDM) for prototyping and creating custom biomedical models and devices.
• Cosmetics & Personal Care: Employed in biodegradable microbeads and delivery systems for active ingredients in skincare formulations.
• Agricultural Films: Used in biodegradable mulch films that decompose in soil, reducing plastic waste and environmental impact.

Quality Control

Our Poly(L-Lactic Acid) is produced under stringent quality management systems to ensure batch-to-batch consistency and high performance. Quality is verified through comprehensive testing, including determination of inherent viscosity, residual monomer content, molecular weight distribution, and thermal properties. Certificates of Analysis (COA) documenting these parameters are provided with each shipment. We can supply grades suitable for research, industrial, and demanding applications requiring compliance with relevant ISO standards and FDA regulations for medical and food contact uses.

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); the container must be kept tightly sealed after opening to prevent moisture uptake, which can affect molecular weight and processability. For long-term storage, consider using desiccants or storing under an inert atmosphere.
