polylactic acid

A single acid molecule has a hydroxyl group and a carboxyl group, a plurality of lactic acid molecules together,magnessium lactate other molecules dehydration condensation,-COOH and-OH in the other molecule dehydration condensation, so that they form a hand in hand a polymer called polylactic acid. Polylactic acid is also known as polylactide, are polyester family. Polylactic acid as the main raw material is a polymer obtained by polymerizing, adequate sources of raw materials and can be recycled. Polylactic acid production process without pollution, and biodegradable products, to achieve the cycle in nature and is therefore ideal green polymer materials.
Polylactic acid (H-[OCHCH3CO] n-OH) good thermal stability, processing temperature 170 ~ 230 ℃, good solvent resistance, can be processed in various ways, such as extrusion, spinning, Calcium lactate , injection blow molding. Products made from poly lactic acid in addition to biodegradation, biocompatibility, gloss, transparency, texture, and good heat resistance, the development of polylactic BrightChina acid (PLA) also have some antibacterial, flame resistance and UV resistance, so the wide range of uses, can be used as packaging materials, fibers and nonwoven materials, mainly used for clothing (underwear, outerwear), industry (construction, agriculture, forestry, paper) and health and other fields.
