Polylactic acid, also known as polylactide, belongs to the polyester family.
Polylactic acid is a polymer obtained by polymerization of lactic acid as the main raw material. The raw materials are abundant and renewable. The production process of polylactic acid is pollution-free, and the product can be biodegradable to realize the circulation in nature, so it is an ideal green polymer material. Thermal stability of poly (lactic acid) (PLA), the processing temperature of 170 ~ 230 ℃, good solvent resistance and processing can be used in a variety of ways, such as extrusion, spinning, biaxial stretching, injection blow molding.
Made from polylactic acid products in addition to the biodegradable, biocompatibility, gloss, transparency, and feel good heat resistance, but also has certain bacteria resistance, flame retardant and ultraviolet resistance, so it is quite widely USES, can be used as packaging materials, such as fiber and nonwoven fabric, now it is mainly used for clothing, underwear, clothing), industry (construction, agriculture, forestry, paper) and health care and other fields.
The PLA's largest manufacturer is NatureWorks of the United States, followed by China's haizheng biota, which currently produces 70,000 tons and 5,000 tons respectively. PLA has many applications and can be used in extrusion, injection molding, film drawing, spinning and other fields.
