Product Name
Polyacrylamide, nonionic, average Mw 7000,000
Description
Acrylamide appears as white crystalline solid shipped either as a solid or in solution. A confirmed carcinogen. Toxic by skin absorption. Less dense than water and soluble in water. May be toxic by ingestion. Used for sewage and waste treatment, to make dyes, adhesives. The solid is stable at room temperature, but upon melting may violently polymerize. Toxic, irritating to skin, eyes, etc.;Acrylamide solution, [aqueous] appears as a colorless aqueous solution of a solid. Often at a concentration of 40% (w/v). Spills can easily penetrate the soil and contaminate groundwater and nearby streams. Used for sewage and waste treatment and to make dyes and adhesives. Toxic, irritating to skin, eyes, etc. Produce toxic oxides of nitrogen when burned.;Acrylamide solution, [flammable liquid label] appears as a solution of a colorless crystalline solid. Flash point depends on the solvent but below 141°F. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion. Used for sewage and waste treatment, to make dyes and adhesives.;DryPowder; Liquid; OtherSolid;Solid;WHITE CRYSTALS.;White crystalline, odorless solid.;White crystalline, odorless solid.
