Polyacrylamide is an important water-soluble polymer, and has valuable properties such as flocculability, densification, shearing, drag reduction, and dispersibility. These properties have various emphasis depending on different derivative ions. Therefore, it is widely used in oil extraction, mineral separation, coal washing, metallurgy, chemical industry, papermaking, textile, sugar making, medicine, environmental protection, building materials, agricultural production and other departments.
Dry powder 25kg/bag, rubber plate 25kg/bag, PVC film for inner bag, plastic woven bag for outer bag.
Polyacrylamide itself is not toxic. Only when the suction volume is greater than five thousandths is it harmful because the absorption of nutrients by the gastrointestinal mucosa is blocked. The residue acrylamide monomer in polyacrylamide is toxic, and its application in food should be strictly controlled. Attention shall be paid to moisture protection during storage and transportation.
