Which is about 1250cm-1 COC asymmetric stretching vibration, 1100cm-1 is approximately symmetrical COC stretching vibration, 1750 cm-1 for the carbonyl absorption peak around, 3500cm-1 absorption peak around the -OH, 2890cm-1 and 2960cm -1 and -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.
