Industrial Uses

1. Polymers & Resins  

  • Monomers for Polymer & Resin Synthesis: PLA serves as a primary monomer in producing biodegradable plastics, offering an environmentally friendly alternative to traditional petroleum-based polymers. Its synthesis involves the polymerization of lactic acid monomers, resulting in materials suitable for applications like packaging and disposable items. 
  • UV-Curable Resins: PLA's favorable melting properties make it a popular choice for fused deposition modeling (FDM) in 3D printing. Its ability to be processed at relatively low temperatures and minimal warping characteristics contribute to its suitability for detailed and precise printing applications. 

 2. Lubrications & Automobiles 

  • Interior Components: PLA is used in manufacturing biodegradable and lightweight interior parts such as dashboard panels and door trims. 
  • Foam Insulation: PLA-based foams serve as thermal and acoustic insulation materials in vehicles. 

3. Construction 

  • PLA-Based Insulation: PLA foams are used for lightweight, biodegradable thermal insulation in buildings. 
  • Concrete Additives: PLA-based biodegradable polymers are explored as additives in construction materials for enhanced durability. 

4. Pharmaceuticals 

  • Drug Delivery Systems: PLA is used in controlled drug release formulations, ensuring a gradual and sustained release of active pharmaceutical ingredients. 
  • Biodegradable Sutures: PLA-based sutures are widely used in surgeries as they gradually dissolve in the body, eliminating the need for removal.
