PLA has good thermal stability, processing temperature of 170-230 ℃, good solvent resistance, and can be processed in various ways, such as extrusion, spinning, biaxial stretching, injection blow molding. Products made from polylactic acid not only have biodegradability, but also have good biocompatibility, glossiness, transparency, hand feel, and heat resistance. They also have certain bacterial resistance, flame retardancy, and UV resistance. Therefore, they are widely used as packaging materials, fibers, and non-woven fabrics. Currently, they are mainly used in fields such as clothing (underwear, outerwear), industry (construction, agriculture, forestry, papermaking), and healthcare.
01
Biomedical field
In the field of biomedicine, polylactic acid materials can be used as drug transport materials, tissue engineering scaffold materials, bone repair materials, and so on.
The medical field was an early application of PLA and its composites. At present, it has carried out extensive basic research and clinical application in orthopaedic surgery, thoracic surgery, maxillofacial surgery, tumor targeted therapy and other fields.
02
Industrial and agricultural sectors
PLA has good plasticity, heat resistance, and physical processing properties. It can be processed into agricultural film to compensate for the fragility and non degradability of traditional film. It can also be processed into accessory engineering materials for the automotive industry, construction ropes, pesticide and fertilizer slow-release materials, etc
03
Food packaging materials
Compared with materials such as polyethylene (PE), polyvinyl chloride (PVC), and polypropylene (PP), polylactic acid (PLA) has good biodegradability, excellent antibacterial and antifungal properties.
POTOP ® Multilayer Coextrusion Casting Production Line can be used to test and process various materials such as plastics and elastomers, and automatically and accurately measure important signals such as melt pressure and temperature during the extrusion process. The electrical components and screw barrel of the extruder are all made of well-known domestic and foreign brand products, and each extruder is equipped with protective covers to improve operational safety; The casting auxiliary machine adopts a horizontal layout for easy operation. Each roller servo motor is independently driven, and the roller seat is guided by linear sliding rails. There is a fine adjustment device to effectively ensure the thickness and dimensional accuracy of the film.
