聚乳酸（PLA）树脂是生产生物塑料最重要的原材料之一

聚乳酸（PLA）是一种广泛使用的热塑性高分子材料

聚乳酸树脂

聚乳酸（PLA）是热塑性塑料中最可生物降解的生物碱之一，由可再生原料如玉米淀粉、木薯、甘蔗、淀粉和葡萄糖发酵获得，并提供两种活性对映体D和L-乳酸以及2-羟基丙酸。乳酸单体的直接缩合用于PLA的生产。在该过程的初始水平，乳酸被低聚成PLA低聚物

PLA聚合物的范围从非晶态玻璃态聚合物到半晶态和结晶性聚合物，其玻璃化转变温度从60-65摄氏度到130-180摄氏度。PLA是一种可选择的半结晶性树脂，不含可选择的成核剂，模具温度决定了非晶态结晶形态的最后部分。与聚丙烯、聚苯乙烯和聚氨酯等传统聚合物相比，聚乳酸具有良好的力学性能。聚乳酸（PLA）树脂

Polylactic Acid (PLA) Resin

Product Details

Polylactic acid (PLA) is one of the most biodegradable biobases in thermoplastics and is obtained from renewable raw materials such as corn starch, tapioca, sugar cane and the fermentation of starch and dextrose and provides two active enantiomers D and L-lactic acids and 2-hydroxypropionic acid. Direct condensation of lactic acid monomers is used for the production of PLA. At the initial level of the process, lactic acid is oligomerized to PLA oligomers.

PLA polymers range from amorphous glassy polymers to semi-crystalline and crystalline polymers with a glass transition from 60-65 degrees Celsius melting temperature to 130-180 degrees Celsius. PLA is a semi-crystalline resin of choice and contains no nucleants of choice, and the mould temperature determines the last part of the amorphous crystalline morphology. Compared to conventional polymers such as polypropylene, polystyrene and polyurethane, PLA has good mechanical properties. Polylactic acid (PLA) resin.
