Polylactic Acid(PLA)

Published on:2022-12-19   Views:532

Polylactic acid, also known as polylactide,Lactic acid was produced by fermentation from corn, potato and other starch based biomass or straw cellulose, which was further purified and polymerized to produce biodegradable polymer material polylactic acid. Polylactic acid has environmental protection, non-toxic, antibacterial, flame retardant and good biocompatibility. Polylactic acid (PLA) has excellent biodegradability and can be completely degraded by microorganisms in the soil to produce CO2 and H2O without polluting the environment. It is considered as the main material to replace petroleum-based plastics (PE, PP, PVC, etc.) and petroleum-based chemical fiber (PET, PTT, PBT, etc.) in the future.

 As a kind of biodegradable material, Polylactic acid has characters of environmental protection, non-toxic, degradable and so on. It is the biodegradable material with the largest output, the widest application range, the highest cost performance and the closest biodegradable materials to petroleum-based polyester in the current international market. PLA through injection moulding and plastic uptake can be processed into membrane, sheet, staple fiber, filament, etc. It has a large scale of demand in the plastic industry, packaging industry, manufacturing and pharmaceutical industry.

Characteristics of PLA

1, It is bio-based polymer materials derived from renewable natural plant resources such as corn, sugar beet and potato through high technology preparation.

2, Bio-based products are suitable for various waste disposal methods: natural decomposition, composting, incineration.

3, Polylactic acid has environmental protection, non-toxic, antibacterial, flame retardant and good biocompatibility, and can be completely biodegradable under normal composting conditions. After the biological degradation it can turn into water and carbon dioxide, zero pollution to the natural ecology.

Product Application:

(1)The green fiber made of polylactic acid can replace petroleum chemical fiber, which is used in underwear, sports and leisure clothing, carpet, curtain, bed, etc.

(2)Through extrusion, injection molding, blow molding and other processes, poly (lactic acid) can be made into green plastics to replace petroleum plastics, used in manufacturing household plastics (cups, plates, boxes, bottles, etc.), industrial plastics (car, boat, aircraft interior and parts, home appliance shells, etc.), film plastics (food packaging film bags, plastic bags, agricultural plastic film, bidirectional stretch film, etc.), medical materials (surgical wires, bone nails, etc.), 3D printing, etc.;

(3)Polylactic acid polyols can be used to produce biological polyurethane, which is used in artificial leather, oil film, hard foam, soft foam and other fields.

(4)As a binder, PLA can be used in producing wood plastic materials which have no bisphenol A, or formaldehyde (urea-formaldehyde resin, phenolic resin), widely used in indoor and outdoor decoration, furniture manufacturing, office furniture and so on.
