Product Details
Polylactic acid (PLA) is a novel bio-based and renewable biodegradable material, derived from renewable plant-based starch sources such as corn and cassava.
PLA powder is widely applied in cosmetics, chemicals, coatings, ceramics and other related fields. PLA fibers feature excellent breathability and sweat-wicking performance, are easy to shape and dye, and have antibacterial and UV-resistant properties. They also demonstrate good compatibility with silk, making them suitable for diverse application scenarios.

Product Application of PLA
PLA (Polylactic Acid) is produced from agricultural crops such as corn and cassava. Through microbial fermentation and extraction, lactic acid is obtained first; followed by refining, dehydration, oligomerization, high-temperature pyrolysis, and polymerization processes to form the final product.
PLA features excellent biodegradability: after disposal, it can be completely degraded by soil microorganisms within one year, decomposing into carbon dioxide (CO₂) and water without causing any environmental pollution. As a member of the aliphatic polyester family, PLA possesses the basic properties of general polymer materials, including good machinability and low shrinkage, which allows it to replace traditional synthetic plastics in most scenarios.
Its application scope is extensive, mainly including: packaging materials, disposable tableware, appliance casings, fiber products, 3D printing consumables, etc.
