Pharmaceutical grade, food suture 3 specifications, the relative molecular shield amount from thousands to more than one million polymer, copolymer and polymer series products, and with its excellent and unique performance in widely used, PVP is divided into confining energy according to its average molecular weight size, usually expressed by the K value, different K values represent the corresponding The average molecular weight range of PVP.
