Product Description
High-Purity Renewable PLLA Polymer support Structure and Versatile Processability for Medical
Biodegradable PLLA Polymer
-
Product Characteristics: Poly-L-Lactic Acid (PLLA) is a high-performance, semi-crystalline bio-polymer sourced from renewable L-lactic acid. With a regular linear molecular structure, uniform molecular weight distribution and ultra-high purity, it contains no toxic ingredients or harmful residues, serving as a sustainable substitute for traditional petroleum-based plastics. This material features outstanding crystallinity, excellent structural rigidity and superior process adaptability. It supports multiple precision molding technologies such as injection molding, extrusion, spinning and electrospinning, fully meeting customized manufacturing demands for medical devices and eco-friendly degradable products.
-
Technical Principle: PLLA is synthesized via dehydration condensation and ring-opening polymerization of L-lactic acid monomers, forming a stable stereoregular molecular structure. Its unique chiral structure grants the material durable mechanical stability and excellent biocompatibility. The core degradation principle lies in the hydrolysis of internal ester bonds under natural or physiological environments. Long-chain polymer molecules gradually break down into tiny lactic acid fragments, which are further metabolized into carbon dioxide and water. The entire degradation process is non-toxic and residue-free, while the ordered crystal structure maintains stable performance throughout the product service cycle.
-
Production Process: PLLA adopts standardized, strictly controlled bio-polymerization production procedures. The process begins with purification of fermented L-lactic acid raw materials to remove impurities and ensure monomer purity. After pre-polymerization via dehydration reaction, high-molecular-weight crude PLLA is formed through precise temperature and pressure-controlled ring-opening polymerization. Subsequent professional devolatilization, secondary purification and crystallization eliminate residual monomers and enhance batch uniformity. The final pelletizing, drying and dust-free sterile packaging procedures guarantee consistent medical-grade purity, stability and reliability for high-end industrial and medical applications.
