CAS;9003-05-8[ Properties ] Polyacrylamide,abbreviation PAM,is a glassy solid,easy to adsorb water ; the absorbing speed are varied with different derivative ions.It is soluble in water and organic solvents as acetic acid,glycol,glycerin and amine.It will be decomposed after long time heating. Decomposed temperature is over 200oC.It can be carbonated into black powder at 210οC without oxygen. It could be made to four series,e.g.,non-ion,cation,anion and mixed cation & anion.[ Uses ] It is an important water-soluble compound with the properties of flocculation,thickening,cut-resisting,block-reducing dispersing,etc ..These properties are varied with different derivative ions.So it is widely used in the field of oil extraction,mining selection,coat washing,metallurgy,chemical,papermaking,sugar refining,pharmaceutical,environment protection,construction materials and agriculture.[ Technical Index ]FF 1.PowderItemsIndexNon-ionCationAnionAppearanceWhite or light yellow powdery particleWhite or light yellow powdery particleWhite or light yellow powdery particleSolid content≥%909090Molecular weight800-10001800-2300300-500Free monomer ≤%0.50.50.5Time for water-soluble(h)111Hydrolysis rate%≤520-305-302.ColloidItemsIndexNon-ionCationAnionAppearanceWhite colloidWhite colloidWhite colloidSolid content ≥%8-308-308-30Molecular weight200-900300-900200-500Free monomer ≤%0.50.50.5Hydrolysis rate%≤55-305-30[ Storage,Transportation & Cautions ] The product itself has no toxicity unless over 0.005 of it is absorbed that will do harm to stomach.The remains of PAM are poisonous .Strictly control the dose in food. Avoid moisture in storage & transport. [ Package ] 25kg/bag (Powder),25kg/bag(Colloid),Internal bag is PVC film bag,external bag is plastic woven bag. AAAAAA
