PLA is an English abbreviated biodegradable plastic polylactic acid,Full name in English:Polylactic acid

Business Scope

PLA is an English abbreviated biodegradable plastic polylactic acid,Full name in English:Polylactic acid

PLA polylactic acid is a polymer obtained by polymerizing lactic acid as a main raw material. Lactic acid is derived from raw materials such as corn and cassava, and is fully sourced and renewable. The production process of polylactic acid is non-polluting, and the product can be biodegraded and realized in the natural world. Therefore, it is an ideal green polymer material.
The advantages of PLA materials
"1. Good biodegradability. After use, it can be completely degraded by microorganisms in the natural world. Eventually, carbon dioxide and water are generated, no pollution is caused to the environment, and no greenhouse effect is caused.
"2. Good mechanical and physical properties, suitable for various processing methods such as blow molding, thermoplastics, etc. It is easy to process and widely used. It can be used to process various plastic products from industrial to civilian use, packaged foods, fast food lunch boxes, no Spinning cloth, industrial and civilian fabrics, and then processed into agricultural fabrics, health fabrics, rags, sanitary products, outdoor UV protection fabrics, tent fabrics, floor mats, etc., the market is very promising.
"3. Good compatibility and degradability. Polylactic acid is also widely used in the medical field. For example, it can produce disposable infusion instruments, exfoliation-free surgical sutures, and low-molecular-weight polylactic acid for drug delivery.
"4. The basic physical properties of polylactic acid (PLA) and petrochemical synthetic plastics are similar, that is to say, polylactic acid can be produced in various applications that plastics can produce. Polylactic acid also has good glossiness and transparency, and utilization. The film made of polystyrene is equivalent and cannot be provided by other biodegradable products.
"5. Polylactic acid (PLA) has the best tensile strength and ductility. Polylactic acid can also be produced in a variety of common processing methods such as: melt extrusion molding, injection molding, blown film molding, foam molding and vacuum molding. It has similar molding conditions to widely used polymers, and it also has the same printing performance as conventional films.
However, the pure PLA material also has some disadvantages, such as weak toughness, poor impact resistance, etc. Therefore, in order to produce better, it must be modified in various ways.
Modified (Modifird): Preserves the original advantages and transforms its disadvantages
Our modified PLA particles:
The color, shape and transparency of the particles can be changed accordingly, without affecting the performance of the particles themselves and the quality of the manufactured products.
Market demand
Industrial market demand
Polylactic acid products have physical properties similar to those of PP plastics, and can be used in a wide range of injection molding products, such as automotive parts and electronic products, after heat-resistant modification. According to the 5% substitution rate of ordinary petroleum-based injection molding materials, the market capacity of polylactic acid will also reach 600,000 tons in this field.
Market demand in agricultural production
The modified polylactic acid has good toughness and can be processed into agricultural mulch to replace the petroleum-based agricultural mulch with slower degradation rate, which can basically eliminate the white pollution caused by the mulching film. In addition, polylactic acid has high practical value in fishing nets and kelp culture nets.
Market demand for daily necessities
Polylactic acid is derived from corn, has good biocompatibility, is non-toxic and harmless to the human body, and has unique advantages in fields such as clothing and food packaging that are closely related to human health. Polylactic acid is now available in supermarket convenience bags, food packaging bags, vegetarian food packaging, disposable tableware. Can also be used for leisure products, such as fishing, outdoor travel equipment. In addition, polylactic acid fiber fabric has strong anti-wrinkle properties, good air permeability, and feels similar to silk. It is comfortable to wear and can be widely used in underwear, outerwear, and sportswear.
Market demand in the field of biomedicine
"6. PLA film has good air permeability, oxygen permeability and dioxygen dioxide permeability, and it also has the property of isolating odors. Viruses and molds are easy to attach to the surface of biodegradable plastics, so there are doubts about safety and hygiene. However, polylactic acid is the only biodegradable plastic with excellent antibacterial and antifungal properties.
