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.
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.
