Properties: Polyacrylamide, abbreviation PAM,is a glassy solid.The speed of absorbing water varless with different derivative.it is soluble in watert and organic solvents,such as acetic acid,glycol,glycerin and amine,it melts after long time heating dissoiving temperature is over 200¡æ,it carbonates to black powder at 210¡æ without oxyen. It could be made to four series e g,mon-ion,cation anion and mixed cation & anion.
Usages: It is an important water-soluble polymer with the properties flocculating,thickening,cut-resisting,block-reducing dispersing,etc.These properties vary with different derivative ions soitis widely used in the field of lil extraction,mining selection,coat washing,metallurgy,cheical,papermaking,sugarrfining,pharmaceutical,envionment protection,construction materials and agricrlture.
Storage & Transport: No toxicity unless over 5% is absorbed that will do harm to stomach.The residue acrylamide is Toric.If is strictly controlled for food application.Avoid moisture in storeage & transport.
Package: 25kg/bag(powder),25kg/bag(colloid) inner bag is PVC film,outer wover plastic bag. Technic Index: Powder
