Product Details
polylactic acid (Polylactic acid , PLA ), also known as polylactide, is a polyester polymerized from lactic acid. Polylactic acid has excellent biodegradability, compatibility and absorbability. Polylactic acid is a non-toxic, non-stimulating synthetic polymer material, its raw material is lactic acid, mainly from starch (such as corn, rice) and other fermentation, can also be obtained from cellulose, kitchen waste or fish waste as raw materials. Compared with traditional plastics, polylactic acid can be degraded into CO 2 and H 2 O by microorganisms and light. Its degradation products are non-toxic and harmless, and will not cause pollution to the environment. The monomer for the production of polylactic acid is lactic acid, which in turn can be produced by fermentation of crops or agricultural by-products such as wheat, rice and sugar beets. Therefore, the raw material for the production of polylactic acid is renewable. As a new biodegradable material, polylactic acid is widely used.
Nantong Kecheng is committed to the research and development, production and sales of efficient internal mixing unit, dense extrusion granulating unit, twin screw granulating unit, single screw granulating unit, double step granulating unit, profile extrusion unit, experimental unit, etc. Kecheng's units are widely used in cable materials, high-filling masterbatch, black and white masterbatch, masterbatch, recycled materials, engineering plastics, general plastics, elastomers, sheet profiles and other fields. We warmly welcome customers, industry experts to visit the company.
