The origin of PLA: It is made from starch extracted from renewable plant resources.
Process: starch raw material - saccharification - glucose - + strain fermentation - to produce high purity lactic acid - by chemical method to synthesize polylactic acid with a certain molecular weight.
Poly (lactic acid) has the following characteristics:
1. Does not pollute the environment, is recognized as environmental protection materials.
2. Excellent performance, not only impact toughness is very good, but also wear resistance, wide temperature range, good dimensional stability, excellent electrical insulation, non-toxicity. Suitable for general equipment processing.
3. The products made from PLA have good biocompatibility, bioabsorbability, bacteriostasis and flame retardancy, and PLA has the best heat resistance among degradable thermoplastic polymer materials.
4.PLA fiber has similar physical characteristics to PET fiber, not only has high crystallinity, but also has the same transparency; Due to its high crystallinity and high orientation, it has high heat resistance and high strength. Without special equipment and operation process, conventional processing technology can be used for spinning.
