Product Details
Polylactic acid (PLA) is an innovative bio-based, renewable and biodegradable polymer synthesized from starch extracted from renewable plant feedstocks including corn and cassava.
PLA powder is a specialty material applied across cosmetics, fine chemicals, coatings, ceramics and other industrial sectors. PLA fibers feature outstanding air permeability and sweat-wicking performance, coupled with favorable moldability and dyeability. They also demonstrate antibacterial and UV-shielding properties, and can be blended with silk fibers for composite applications.

Product Application
Polylactic acid (PLA) is manufactured from agricultural feedstocks including corn and cassava. Lactic acid is first obtained via microbial fermentation and extraction processes, followed by sequential refining, dehydration, oligomerization, high-temperature pyrolysis and polymerization to yield the final PLA product.
Boasting exceptional biodegradability, PLA can be fully broken down by soil-borne microorganisms within one year after disposal, generating only carbon dioxide and water without leaving environmental contaminants. As an aliphatic polyester, PLA possesses fundamental properties typical of conventional polymeric materials. It features favorable processability and low shrinkage, making it compatible with processing techniques applicable to most synthetic plastics. Accordingly, it is extensively adopted in the manufacture of packaging materials, single-use tableware, electrical appliance housings, textile fibers, 3D-printing filaments and other products.
