Description

Poly(L-Lactide Glycolide) is a biodegradable, biocompatible copolymer synthesized from L-lactide and glycolide monomers. This material is engineered to provide controlled degradation rates and mechanical properties, making it a cornerstone for advanced, resorbable medical and pharmaceutical applications. It is essential for manufacturers in the biomedical, pharmaceutical, and controlled-release agrochemical sectors seeking reliable, high-purity polymer matrices.

Application

• Resorbable Medical Devices: Key component in the manufacture of surgical sutures, staples, bone screws, plates, and other orthopedic fixation devices.
• Drug Delivery Systems: Matrix material for microspheres, nanoparticles, and implants designed for sustained or targeted release of active pharmaceutical ingredients (APIs).
• Tissue Engineering Scaffolds: Used to create three-dimensional, porous scaffolds that support cell growth and tissue regeneration.
• Veterinary Medicine: Employed in long-acting injectable formulations and implantable devices for animal health.
• Controlled-Release Agrochemicals: Carrier for the encapsulation and gradual release of pesticides, herbicides, or fertilizers.
• Advanced Wound Care: Basis for bioresorbable dressings, hemostats, and adhesion barriers.

Quality Control

Our Poly(L-Lactide Glycolide) is produced under strict quality management systems. Each batch is characterized for critical parameters including monomer ratio (L:G), inherent viscosity, molecular weight distribution, residual monomer content, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with cGMP, ISO 13485, and relevant pharmacopeial guidelines for medical-grade 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, inert conditions (e.g., nitrogen atmosphere) after opening to prevent hydrolysis and molecular weight degradation. For long-term storage, consider refrigeration at 2-8°C.
