Medical polymer "Poly-L-lactic acid (PLLA)"
Recommended for applications such as new medical devices! A polymer with flexible processing characteristics.
Poly-L-lactic acid (PLLA) is obtained by using lactide (the cyclic dimer of lactic acid) as a monomer and performing ring-opening polymerization. L-lactic acid and D-lactic acid have the same chemical properties, differing only in their stereostructure. Therefore, the PLLA polymer and PDLA polymer differ only in their stereostructure, with their properties being almost unchanged. However, the PDLLA polymer exhibits different properties due to its molecular chain stereostructure, which is distinct from both PLLA and PDLA polymers. Our BioDegmer is produced in facilities that comply with ISO 13485, can be processed into a wide variety of shapes, and is used in a broad range of applications in the medical field. [Features] - Mainly processed into biodegradable bone fixation materials - Also used as anti-adhesion membranes and stents - Flexible processing characteristics - Capable of being processed into various shapes - Properties: crystalline, transparent, heat-resistant (when stereocomplexed) *For more details, please refer to the PDF document or feel free to contact us.
