Typical Specification Of Poly(D-lactide)
Product characteristics and Application：By poly (D-lactide） made products biological compatibility is good, after the in vivo degradation product by the metabolism out of the body, no harmful and toxic side effects on the human body. At present, it is widely used in the fields of medicine, such as disposable infusion apparatus, free disassembly type suture; drug controlled release, sustained release agent packaging; scaffolds for tissue engineering, bone fixation and bone repairing material, injection with of microcapsules and microspheres, implants and animal organs elastomer material support.
Processing technology：Injection molding、Melt spinning Etc。

Poly(L-lactide) Infrared Spectrum：
Which is about C-O-C, the asymmetric stretching vibration peak of 1100cm-1 is about C-O-C, which is about cm-1 symmetric stretching vibration peak, around 1750 3500cm-1 for the carbonyl absorption peak, 1250cm-1 or so is the absorption peak of -OH, 2890cm-1 and 2960cm-1 are -CH3.
■ 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.
