Description

Poly(Dl-Lactide) Inherent Viscosity is a high-purity, synthetic polymer derived from lactic acid, characterized by its specific inherent viscosity (IV), which is a critical indicator of its molecular weight and performance in end-use applications. This material is essential for creating biodegradable and biocompatible structures with controlled degradation rates and mechanical properties. It is primarily required by manufacturers in the pharmaceutical, medical device, and advanced biomaterials sectors for applications demanding precise polymer performance.

Application

• Controlled-Release Drug Delivery Systems: As a key excipient for formulating microspheres, implants, and nanoparticles that provide sustained API release.
• Absorbable Medical Devices: Used in the production of surgical sutures, orthopedic fixation devices (pins, screws), and tissue engineering scaffolds.
• 3D Printing of Biomedical Models: Serves as a filament material for fabricating patient-specific anatomical models and prototypes for surgical planning.
• Biodegradable Packaging: For high-value, eco-friendly packaging solutions in niche markets where composability is required.
• Advanced Biomaterial Research: A fundamental polymer for R&D in developing new resorbable polymers, hydrogel composites, and smart material systems.

Quality Control

Our Poly(Dl-Lactide) is manufactured under strict quality management systems. Each batch is tested to ensure critical parameters such as inherent viscosity, residual monomer content, and molecular weight distribution meet stringent specifications. Certificates of Analysis (COA) detailing these results are provided and can be tailored to support regulatory filings for pharmaceutical (GMP) and medical device applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); prolonged exposure to high humidity should be avoided to prevent hydrolysis and viscosity loss. For long-term storage, consider using desiccants or an inert atmosphere.
