Description

Polylactic Acid CAS NO 26023-30-3 is a biodegradable, thermoplastic aliphatic polyester derived from renewable resources like corn starch or sugarcane. This biopolymer is a cornerstone material for sustainable manufacturing, offering a viable alternative to traditional petroleum-based plastics. It is essential for industries focused on reducing environmental impact, including packaging, biomedical engineering, and 3D printing.

Application

• Biodegradable Packaging: Used in films, containers, and disposable tableware as an eco-friendly alternative to conventional plastics.
• Medical & Biomedical Devices: Ideal for resorbable sutures, drug delivery matrices, orthopedic implants, and tissue engineering scaffolds due to its biocompatibility.
• 3D Printing (FDM/FFF): A popular filament material for creating prototypes, models, and functional parts with good surface finish and dimensional stability.
• Textiles: Employed in the production of fibers for non-woven fabrics, apparel, and upholstery.
• Agriculture: Used in mulch films, plant pots, and controlled-release systems for fertilizers and pesticides.
• Consumer Goods: Found in items like disposable cutlery, cups, and compostable bags.

Quality Control

Our Polylactic Acid is manufactured under stringent quality management systems. Each batch is tested for critical parameters including molecular weight distribution, optical purity (D-isomer content), thermal properties, and residual monomer levels to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); prolonged exposure to high humidity should be avoided to prevent hydrolysis and molecular weight degradation.
