Biodegradable Resins Polylactic Acid (PLA), No Harm To Environment And Ecological Material
What is PLA?
PLA takes annually renewable resources – corn, cassava and other plants as raw material. After fermentation by microorganisms, lactic acid will be extracted, then PLA will be produced through a process of refining, dehydration polymerization, high temperature pyrolysis and final polymerization.
What is advantage of PLA?
PLA has excellent biodegradable property. After disposal, within one year, it can be degraded into carbon dioxide and water by microorganisms in the soil, and do no harm to our environment. PLA is a kind of aliphatic polyester with basic characteristics of general micromolecule materials. PLA has good machanical properties, low shrinkage, and is competent to the application of most synthetic plastics.
Because PLA derives from renewable plant resoures but not the petroleum-based traditional plastics, so it can truely realize energy-saving and enviromental protection, and PLA is considered to be the most promising new "ecological material".
PLA application
PLA widely used in the production of package materials, disposable tableware, household electrical appliance shell, fiber, 3D supplies etc.
