Typical Specification Of Poly(p-dioxanone)
Product characteristics and Application：By poly (p-dioxanone) made of bio 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, absorbable suture, orthopaedics fixation materials and tissue repair materials such as orthopaedic screws, fixed bolt, pin, anchor, hoop and bone plate fixing device, hemostatic forceps, hemostatic plaster, suture clamp, the sieve of medicinal and medical adhesive.
Processing technology：Injection molding、Melt spinning Etc。

Poly(1,4-dioxan-2-one) Infrared Spectrum：
The 1736cm-1 about carbonyl C = O stretching vibration absorption peak; 1432cm-1 about methylene CH2 bending vibration absorption peak; 122111341052 cm-1 for C-O stretching vibration absorption peak; broad peak appeared around 3456cm-1 OH stretching vibration peak, indicating that the polymer containing hydroxyl end groups.
■ 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.
