Poly L-Lactide (PLLA) is a biodegradable and biocompatible polymer derived from renewable lactic acid sources. It is widely used in medical, pharmaceutical, and industrial applications due to its high tensile strength, thermal stability, and controlled degradation properties. With excellent mechanical performance, PLLA is an ideal material for absorbable sutures, orthopedic implants, drug delivery systems, and tissue engineering scaffolds. In industrial applications, it serves as a sustainable alternative to conventional plastics, offering eco-friendly solutions for packaging and 3D printing.
Our PLLA is available in different molecular weights to meet specific application requirements, ensuring optimal performance in processing techniques such as extrusion, injection molding, and electrospinning. To maintain stability and prevent hydrolysis, the product is vacuum-sealed and packaged in moisture-proof materials. Bulk supply options are available for industrial production, with reliable shipping and global distribution networks ensuring consistent quality and timely delivery.

FAQ
Most frequent questions and answers
PLLA is known for its high mechanical strength, slow degradation rate, and excellent biocompatibility. Customers often ask about:
Tensile strength and toughness for structural applications.
Degradation time for medical and biodegradable applications.
Thermal properties, such as glass transition temperature (Tg) and melting point (Tm).
PDLA (Poly D-Lactide): A stereoisomer of PLLA with similar properties but often blended with PLLA for enhanced crystallinity.
PDLLA (Poly D,L-Lactide): An amorphous polymer with faster degradation but lower mechanical strength.
Yes. We offer custom molecular weight options, copolymerization with other monomers (e.g., glycolide, caprolactone), and formulation adjustments to optimize strength, degradation rate, and thermal properties for different uses.
PLLA degradation is influenced by:
Molecular weight (higher MW degrades slower).
Crystallinity (more crystalline structures degrade slower).
Processing conditions and environment (temperature, humidity, and pH affect hydrolysis rates).
Yes, our high-purity PLLA meets medical-grade standards and is commonly used in FDA-approved biodegradable implants, sutures, and drug delivery systems.
