polyacrylamide white powder molecular weight:300million-2000million solid content: more than 90%

Product Introduction: Polyacrylamide,addreviation PAM,is a glassy solid,apt to water absorbing;the speed of absorbing water varies with different derivative ions.It is soluble in water and organic solvents as acetic acid,glycol,glycerin and amine.It will dissolve after long time heating.Dissolving temperature is over 120οC.It carbonates to black powder at 210οC.It carbonates to black power at 210οC without oxygen.It could be made to four series,e.g.,non-ion,cation,anion and mixed cation & anion.

Usage:

It is an important water-soluble compound with the properties of flocculation,thickening,cut-resisting,block-reducing dispersing,etc..These properties vary with different derivative ions.So it is widely used in the field of oil extraction,mining selection,coat washing, metallurgy, chemical, papermaking,sugarrefining,pharmaceutical,environment protection,construction materials and agriculture.Main Technical Indexes:
