Polylactic acid
Product description:

Polylactic acid is a new type of bio-based and renewable biodegradable material made from starch raw materials proposed by renewable plant resources such as corn and cassava. The starch raw material is obtained by saccharification to obtain glucose, and then glucose and a certain strain are fermented to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under certain conditions, and finally produces carbon dioxide and water without polluting the environment. This is very beneficial to the environment and is recognized as an environmentally friendly material.
Polylactic acid has good thermal stability, processing temperature of 170-230 ° C, good solvent resistance, and can be processed in various ways, such as extrusion, spinning, biaxial stretching, and injection blow molding. In addition to biodegradability, products made of polylactic acid have good biocompatibility, gloss, transparency, hand and heat resistance, and also have certain bacteria resistance, flame retardancy and UV resistance. Widely used as packaging materials, fibers and nonwovens, etc. Currently, it is mainly used in emerging fields such as clothing (underwear, outerwear), industry (construction, agriculture, forestry, papermaking), medical and health, and 3D printing consumables.
