Description

Poly(D-Lactide) is a high-purity, synthetic polymer derived from D-lactic acid. This material is critical for applications requiring specific stereochemistry and controlled degradation profiles, offering superior performance in advanced medical and packaging solutions. It is essential for manufacturers in the biomedical, pharmaceutical, and sustainable packaging industries seeking reliable, high-quality polymer feedstocks.

Application

• Biomedical Implants: Used as a raw material for bioresorbable screws, pins, and plates due to its predictable degradation rate and biocompatibility.
• Controlled Drug Delivery: A key polymer for formulating microspheres, nanoparticles, and implants designed for sustained and targeted release of active pharmaceutical ingredients.
• Surgical Sutures: Manufactured into high-strength, absorbable sutures that provide temporary wound support before being metabolized by the body.
• Tissue Engineering Scaffolds: Serves as a structural matrix to support cell growth and tissue regeneration in advanced medical therapies.
• High-Barrier Packaging: Utilized in specialty films and coatings for food and electronics packaging where moisture and gas barrier properties are paramount.
• 3D Printing Filaments: Employed in fused deposition modeling (FDM) for creating precise, medical-grade prototypes and custom devices.

Quality Control

Our Poly(D-Lactide) is manufactured under strict quality management systems. Each batch is tested to ensure compliance with critical parameters such as inherent viscosity, residual monomer content, and optical purity. Certificates of Analysis (COA) detailing specific results for molecular weight, thermal properties, and sterility (where applicable) are provided to guarantee batch-to-batch consistency and suitability for demanding 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 under dry conditions, preferably with desiccant, to prevent hydrolysis and molecular weight degradation. For long-term storage, consider inert atmosphere packaging.
