Poly D-Lactide (PDLA) is a biodegradable and biocompatible polymer made from D-lactide. It offers high crystallinity, excellent thermal stability, and good mechanical properties, making it suitable for various industrial and medical applications. PDLA is often used to enhance the performance of polylactic acid (PLA) by improving heat resistance and structural strength.
This polymer is widely applied in biodegradable plastics, medical implants, and drug delivery systems. In combination with Poly L-Lactide (PLLA), it forms stereocomplex PLA, which has superior thermal and mechanical properties compared to regular PLA. This makes it an ideal material for high-performance biodegradable products.
PDLA is available in different molecular weights to meet specific processing needs, including extrusion, injection molding, and 3D printing. It is packaged in moisture-proof, vacuum-sealed containers to ensure stability and prevent degradation. Bulk supply options are available for industrial production, with reliable global shipping to support large-scale manufacturing.
