Product Summary
Polylactic Acid (PLA) Powder is a highly versatile and ecologically significant thermoplastic biopolymer. Unlike traditional petroleum-based plastics, PLA is derived from renewable resources like corn starch, making it biodegradable and compostable under industrial conditions.
This fine powder form is essential for applications requiring high surface area, precise material loading, or specialized processing methods. It delivers excellent mechanical strength, transparency, and processability, positioning it as a sustainable alternative to conventional petrochemical plastics across multiple industries.
Primary Applications
Polymers & Biomaterials:
3D Printing/Additive Manufacturing: Used to prepare filaments, resins, or directly in Selective Laser Sintering (SLS) and other powder-based techniques, prized for its excellent resolution and low warping.
Biodegradable Packaging: Used in films, coatings, and molding applications for food and consumer goods where sustainability is paramount.
Biochemical / Life Sciences:
Drug Delivery Systems: Utilized in controlled-release formulations, microcapsules, and implants due to its biocompatibility and controlled degradation rate in vivo.
Tissue Engineering: Used as a scaffold material for cell culture and regenerative medicine due to its non-toxicity and mechanical properties.
Materials Chemistry & Functional Surfaces:
Composite Formulation: Blended with natural fibers, nanoparticles, or other materials to enhance properties while maintaining biodegradability.
Coatings and Adhesives: Used in specialized coating formulations where a biodegradable, food-contact safe material is required.
Ordering and Customization
Stereochemistry: Available in PLLA, PDLA, and P(D,L)LA grades to control crystallinity, thermal resistance, and degradation rate.
Particle Size: Customizable particle size distribution to meet the specific requirements of SLS printers, compounding processes, or microsphere formation.
