1、聚乳酸(PLA):PLA具备无毒性无刺激性、优良的生物组织相容性、强度高、可加工性好,可生物发生降解等特点,制成的片材、纤维、薄膜历经热成形、纺丝等二次生产加工后普遍问题用以提高包装、纺织品和医疗设施设备等领域,其废弃物可通过影响微生物转化成水和二氧化碳。

1. Polylactic acid (PLA): PLA has the characteristics of non-toxic, non irritating, excellent biocompatibility, high strength, good processability and biodegradability. The sheets, fibers and films made of PLA have common problems after secondary production and processing such as hot forming and spinning, so as to improve the quality of packaging, textiles, medical facilities and equipment, Its waste can be converted into water and carbon dioxide by affecting microorganisms.
2、聚羟基脂肪酸酯(PHA):PHA是由许多不同微生物通过生成的一种具有细胞内聚脂,是一种纯天然的高分子建筑材料作为生物工程材料,同时企业具备这些优良的生物相容性、生物可降解性和塑料的热处理工艺性能,可作为生物医用纳米材料和生物可降解包装设计材料。
2. Polyhydroxyfatty acid ester (PHA): PHA is an intracellular polyester produced by many different microorganisms. It is a pure natural polymer building material as a bioengineering material. At the same time, the enterprise has these excellent biocompatibility, biodegradability and heat treatment process performance of plastics, It can be used as biomedical nano materials and biodegradable packaging design materials.

3、聚丁二酸丁二醇酯(PBS):PBS综合系统性能更加出色,性价比是否合理,主要功能用途也是极其社会普遍,可用以实现包装、餐具、化妆品瓶及药物瓶、一次性医用品、农用薄膜、农药及化肥缓释材料、生物处理医疗高分子结构材料等领域。
3. Polybutylene succinate (PBS): PBS comprehensive system has better performance and reasonable cost performance. Its main functions and uses are also very common in society. It can be used to realize the fields of packaging, tableware, cosmetic bottles and drug bottles, disposable medical products, agricultural films, pesticide and fertilizer release materials, biological treatment, medical polymer structural materials and so on.
4、聚己内酯(PCL):PCL除了必须具备热固性塑料易加工的特性外,还有一些生物可降解性、生物相容性、形状温控记忆性等特性,主要运用为可控释药物治疗载体,完全可降解塑料手术缝合线等医用材料。
4. Polycaprolactone (PCL): in addition to the easy processing characteristics of thermosetting plastics, PCL also has some characteristics such as biodegradability, biocompatibility and shape temperature control memory. It is mainly used as controlled-release drug treatment carrier, fully degradable plastic surgical suture and other medical materials.
