Description

Poly(L-Lactide) CAS NO 26161-42-2 is a high-purity, biodegradable polymer derived from L-lactic acid. This material is essential for applications requiring excellent biocompatibility, controlled degradation, and high mechanical strength. It is a critical raw material for manufacturers in the medical device, pharmaceutical, and sustainable packaging industries seeking reliable, high-performance biopolymers.

Application

• Medical Devices: Used in the production of bioresorbable sutures, surgical meshes, orthopedic fixation devices (pins, screws), and tissue engineering scaffolds.
• Pharmaceuticals: Serves as a key excipient in controlled-release drug delivery systems, including microspheres, implants, and nanoparticle formulations.
• Sustainable Packaging: A primary component for manufacturing compostable films, rigid containers, and other eco-friendly packaging solutions.
• 3D Printing (Additive Manufacturing): Utilized as a filament or resin in biomedical 3D printing for creating custom implants and anatomical models.
• Specialty Fibers & Nonwovens: Processed into fibers for agricultural textiles, hygiene products, and filtration media.
• Cosmetics & Personal Care: Employed in biodegradable microbeads and encapsulation systems for active ingredients.

Quality Control

Our Poly(L-Lactide) is manufactured under stringent quality management systems. Each batch is characterized for critical parameters including inherent viscosity, residual monomer content, molecular weight distribution, and thermal properties to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We can support compliance requirements for medical and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent hydrolysis and molecular weight degradation. For long-term storage, consider using desiccants or inert atmosphere packaging.
