POLY(L-LACTIDE GLYCOLIDE) Usage

1.Used in surgical sutures, anti-adhesion membranes and tissue engineering scaffolds.

2.Compared with PLA, polymer degradation time can be controlled according to different GA content, and the material is soft and elastic.

3.Different types of PDLGA can be prepared in different monomer ratios, for example: PDLGA 75:25 means that the polymer consists of 75% lactic acid and 25% glycolic acid. The degree of degradation of PDLGA varies with monomer ratio, and the larger the proportion of glycolide, the more easily it degrades.

4.Used as a medical surgical film, skin transplantation, wound suturing, microcapsule for injection, in vivo implantation, micro Excipients for sustained-release preparations and porous scaffolds for tissue engineering cell culture
