PLA (It is also called Polylactic Acid, Poly( Lactic Acid) or Polylactide) is a new type of bio-based, bioactive thermoplastic and renewable biodegradable material which is made from starch raw materials, such as corn starch, cassava roots, chips or starch, or sugarcane and other renewable plant resources.——
PLA (It is also called Polylactic Acid, Poly( Lactic Acid) or Polylactide) is a new type of bio-based, bioactive thermoplastic and renewable biodegradable material which is made from starch raw materials, such as corn starch, cassava roots, chips or starch, or sugarcane and other renewable plant resources. In 2010, PLA had the second highest consumption volume of any bioplastic of the world.
Starch raw material through saccharification to obtain glucose, and then by the fermentation of glucose and a certain strain of lactic acid, and then synthesized by chemical synthesis of a certain molecular weight polylactic acid. It has good biodegradability and can be completely degraded by microorganisms in nature under certain conditions, resulting in the formation of carbon dioxide and water, without polluting the environment, which is very advantageous to protect the environment and is recognized as an environmentally friendly material.
PLA is processed by extrusion such as 3d printing, injection molding, film and sheet casting, and spinning, providing
Access to a wide range of materials. 3D printed Human skull with data from Computed tomography.
Transparent PLA. PLA is used as a feedstock material in desktop fused filament fabrication 3D printers. PLA printed solids can be encased in plaster-like moulding materials, then burned out in a furnace, so that the Resul Ting void can be filled with molten metal.
This is known as "Lost PLA casting", a type of investment casting. Being able to degrade into innocuous lactic acid, PLA was used as medical implants in the form of anchors, screws, plates, Pins, rods, and as a mesh. [depending] on the exact type used, it breaks down inside the body within 6 months to 2 years. This gradual degradation are desirable for a support structure, because it gradually transfers the load to the body (e.g. T He bone) as that area heals. The strength characteristics of PLA and PLLA implants is well documented.
PLA can also be used as a decomposable packaging material, either cast, injection-molded, or spun. Cups and bags has been made from this material. In the form of a film, it shrinks upon heating, allowing it to be used in shrink tunnels. It is useful for producing loose-fill packaging, compost bags, food packaging, and disposable tableware. In the form of fibers and nonwoven fabrics, PLA also have many potential uses, for example as upholstery, disposable garmen TS, awnings, feminine hygiene products, and diapers. Thanks to its bio-compatibility and biodegradability, PLA have also found ample interest as a polymeric scaffold for drug delivery purposes.
More application we are still developing.
