Chemical Properties:
  • 2015 REACH is the production of polylactic acid using lactic acid as raw material. Traditional lactic acid fermentation mostly uses starch raw materials. At present, the United States, France, Japan and other countries have developed the use of agricultural and sideline products as raw materials to ferment lactic acid to produce polylactic acid, the English abbreviation PLA. The main methods are:
  • The direct polycondensation method uses a solvent to make dehydration polycondensation under vacuum. Japan has done a lot of research in this area, but ultimately failed to achieve industrialization.
  • The two-step method generates cyclic dimer lactide from lactic acid, which is then ring-opened and polycondensed into PLA. This technology is relatively mature, and the process used by NatureWorks in the United States to produce PLA is this process. The PLA production technology jointly developed by China’s Hai Chemicalbook and the Chinese Academy of Sciences is also similar. The main process is that the raw materials are fermented by microorganisms to produce lactic acid, and then refined, dehydrated, oligomerized, and pyrolyzed, and finally polymerized into polylactic acid PLA.
  • Abbreviated as PLA, it is a type of polymer polymerized by the fermentation product of microorganisms L-lactic acid as monomer. It is non-toxic, non-irritating, has good biocompatibility, can be biodegraded and absorbed, has high strength, and does not pollute. The environment can be plastically processed into a Chemicalbook-type polymer material. It has good mechanical properties, high impact strength, high flexibility and thermal stability, does not change color, has good permeability to oxygen and water vapor, and has good transparency, antibacterial and mildew resistance, and a service life of up to 2 ~3 years.
  1. Extrusion-grade resin is the main application of PLA, mainly used for packaging fresh fruits and vegetables in large supermarkets. This type of packaging has become an important member of the European market chain; secondly, it is used for packaging of electronic products that promote safety, energy saving and environmental protection. superior. In these applications, PLA’s high transparency, high gloss, high rigidity and other advantages are vividly reflected, and it is now the dominant direction of PLA applications. In addition, the application of extrusion-grade resin in horticulture has also begun to gain attention, and it has been applied in slope greening, sandstorm management and other fields.
    However, the extrusion processing of PLAChemicalbook is not easy. It is only suitable for processing on some advanced PET extrusion molding machines, and the thickness of the extruded sheet is generally only in the range of 0.2-1.0mm. The processing process is particularly sensitive to moisture content and processing temperature.
  2. During extrusion processing, the moisture content is generally required to be less than 50×10-6, which puts forward new requirements for the drying system and temperature control system of the equipment. During the processing process, if there is no suitable crystallization equipment, the recycling of scrap is also a big problem, which is the reason why there are a large amount of PLA scrap in circulation on the market.
