Food Grade PVPP/ E1202
CTFAName: Polyplasdone, PVPP
CAS NO: 25249-54-1
CHEMICAL DESCRIPTION:Croslinked PVP,Crospovidone,Insoluble PVP,Pollyvinylpolypyrrolidone
Physical Properties:
Exists as white or slight yellow, free flowing hygroscopic power with odourless or faint characteristic smell. It's insoluble in water, alkali, acid and common organic reagents Stereoscan photographs show that it is voluminous particulars and has large total surface and lots of porosity which is between 2-10nm. It can swell in water easily and can complex with polyphenol, carboxylic acids and other low molecular weight compounds. PVPF can only be used once and PVPR can be reused after regenerated.
