Typical Specification Of Poly(D,L-lactide-co- glycolide)

Product characteristics and Application：PLGA is a random copolymer, amorphous polymers, are widely used in surgical sutures, anti-adhesion membrane, tissue engineering scaffold. Compared with the PLA, depending on the GA content can be controlled polymer degradation time, soft and flexible material. The monomers may be prepared in different proportions of the different types of PLGA, for example: PLGA 75:25 polymer consists of 75% indicates that 25 percent lactic acid and glycolic acid composition. There are differences in the degree of degradation of PLGA than with the different monomers, the greater the proportion of glycolide more easily degradable.

Processing technology：Injection molding、Melt spinning Etc。

Storage Condition：

■ According to biodegradable materials,in order to ensure product quality,a special package to aviod water is very neccessary.

■ We filled high qurity dry nitorgen in the Polyethylene bag for hot plastic, the outer lining of thermal plastic foil pouch, built-in desiccant. All the packing is done in a highly clean room.

■ All of the polymers should be stored at 0 ° C or less, and should prevent hydrolysis. Before opening, the product should be allowed to adjust to room temperature to avoid condensation polymer concentrate combined with moisture in the bag. To re-opened after the product packaging sealing, must be of high purity dry nitrogen filled to prevent moisture generated in the bag.
