Absorbable medical devices (PLLA‑based substrate)
‑ Orthopedics: Absorbable bone pins, bone screws, fixation plates and bone anchors, which degrade gradually in‑vivo after surgery to avoid secondary removal operations;
‑ Surgery: Absorbable surgical sutures and surgical meshes;

 

Drug‑delivery carriers
‑ Synthesize PLA and PLGA copolymers for fabrication of drug‑loaded microspheres, nanoparticles and implants to achieve long‑term sustained release (peptides, hormones, anti‑tumor drugs);
‑ Tissue‑engineering scaffolds: Porous scaffold materials for bone, cartilage and skin repair.

 

Organic synthetic intermediate: Used for the synthesis of chiral polyesters and block copolymers (e.g. PLA‑PEG) for biomedical material R&D.

Synthesis of PLLA (Poly‑L‑lactide) resin
‑ Biodegradable plastics: Disposable tableware, food packaging films and shopping bags;
‑ 3D‑printing consumables: PLA printing filaments;
‑ Fiber & textile industry: Biodegradable fibers, non‑woven fabrics and disposable textile materials.

 

Copolymerization modification
‑ Copolymerize with caprolactone, ethylene glycol, etc. to produce modified biodegradable polyesters;
‑ Chain extender for polyurethane to enhance the biodegradability of materials;
‑ Compatibilizer for polymer blending to improve compatibility between PLA and other plastics.
