Study of the degradation properties of polylactic acid

The degradation of polylactic acid (PLA) is highly related to the molecular weight size, the shape prepared into and the environment of degradation, which can be hydrolysis, enzyme, acid, alkali and alcohol.

Jinan Daigang Biotechnology Co., Ltd. is a high-tech company specializing in the production, sales and service of medical biodegradable materials. The company is located in Jinan City, Shandong Province, which has a beautiful environment, strong technical force, a high-quality, practical high-tech R & D team, advanced R & D means, with many years of experience in the development of medical biodegradable materials, and has a 100,000 level purification room at the same time.
