What is polylactic acid (PLA)
Time：2020-11-23
Polylactic acid (PLA) uses corn, cassava and other crops as raw materials to obtain lactic acid through microbial fermentation and extraction, and then is refined, dehydrated and oligomerized, pyrolyzed, and polymerized. PLA has excellent biodegradability. It can be completely degraded by microorganisms in the soil within one year after being discarded, generating CO2 and water, without polluting the environment.
PLA itself is an aliphatic polyester, has the basic characteristics of general polymer materials, has good mechanical processing properties, low shrinkage, and can be used for most synthetic plastics. It is widely used to make packaging materials, disposable tableware, and home appliances. Shell, fiber, 3D consumables, etc.
