The Process Of Polylactic Acid

100% Biodegradable PLA production is based on lactic acid, and traditional lactic acid fermentation mostly uses starchy raw materials. At present, the United States, France, Japan and other countries have developed the use of agricultural and sideline products as raw materials for the production of lactic acid, thereby producing polylactic acid.

Today we share the process of poly lactic acid PLA and hope to help you.

Draw Materials

After the shell crop such as corn is crushed, the starch is extracted therefrom, and then the starch is made into unrefined glucose. Many high technologies have reduced the crushing process and extracted raw materials directly from a large number of crops.

Fermentation

Glucose is fermented in a manner similar to the production of beer or alcohol, and glucose is fermented to become similar to lactic acid used in human muscle tissue.

Intermediate Product

The lactic acid monomer is converted into an intermediate product, a water-reduced lactic acid, that is, lactide, in a special concentration process.

Polymerization

After the lactide monomer is vacuum-purified, the ring-opening operation is completed in a dissolution process without using a solvent to polymerize the monomer.

Polymer Modification

Due to the difference in molecular weight and crystallinity of the polymer, the material properties can be changed greatly, so the PLA is modified differently for different applications.
