Applications
PLA is produced from agricultural crops such as corn and cassava through microbial fermentation and extraction to obtain lactic acid. This is followed by refining, dehydration, oligomerization, high-temperature pyrolysis, and polymerization. PLA exhibits excellent biodegradability; it can be completely degraded by soil microorganisms within one year of disposal, producing CO2 and water without causing environmental pollution. PLA itself belongs to the aliphatic polyester family and has the basic characteristics of general polymer materials. It has good machinability, low shrinkage, and can be used for most synthetic plastics. It is widely used in the production of packaging materials, disposable tableware, appliance casings, fibers, 3D consumables, etc.
