Application of polylactic acid

Polylactic acid (PLA) is a new type of biodegradable material, which has good biodegradability. After use, it can be completely degraded by microorganisms in nature under specific conditions, and finally produces carbon dioxide and water without polluting the environment. The environment is very favorable, and it is recognized as an environmentally friendly material.

Polylactic acid has good thermal stability, the processing temperature is 170-230 ° C, and it has good solvent resistance. It can be processed in various ways, such as extrusion, spinning, biaxial stretching, and injection blow molding. In addition to being biodegradable, products made of polylactic acid have good biocompatibility, gloss, transparency, feel and heat resistance, and also have certain bacteria resistance, flame retardancy and UV resistance, so they are very useful. It is widely used as packaging materials, fibers and nonwovens, etc. It is mainly used in clothing (underwear, outerwear), industry (construction, agriculture, forestry, paper) and medical and health fields.
