Polyacrylic Acid/PAA cas:9003-01-4 in stock

Poly acrylic acid (PAA) cas:9003-01-4 is a colorless to pale yellow transparent liquid with a content of 30%; It is easy to dissolve in water and has good dispersibility. It evenly disperses microcrystals or sediment in water to prevent sedimentation and scaling. The pH value of polyacrylic acid is 2.5-4.5, and the density is 1.10 g/cm ³. The free monomer content of polyacrylic acid is relatively low, and its ultimate viscosity is between 0.06 and 0.12 dl · g ⁻¹, so its stability and performance are very good.Polyacrylic acid (PAA) has strong water absorption and retention capabilities, and is therefore widely used in industries such as pharmaceuticals, cosmetics, and water treatment. PAA is mainly used for the production of superabsorbent polymers (SAP). These materials can absorb and retain a large amount of moisture relative to their own mass, and are used to produce products such as diapers, adult incontinence products, and feminine hygiene products. The carboxyl group in PAA attracts water molecules and expands to form gel to capture liquid.
