  • Is polyacrylic acid a hygroscopic polymer?
  • Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC. At temperatures above 200 to 250oC, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperatures. Concentrated solutions of PAA in water is thixotropic in nature.
  • What is polyacrylic acid/sodium polyacrylate (Paa) used for?
  • Polyacrylic acid/sodium polyacrylate (PAA, PAAS) is used as antiscalant in cooling water systems. It is also used in pulp and paper processing and reverse osmosis systems and cleaning formulations. 0.5 max. 3.0 max. Polyacrylic acid/sodium polyacrylate (PAA, PAAS) is a harmful material. Avoid contact with skin and eyes. Avoid breathing vapor.
  • How much polyacrylic acid/sodium polyacrylate is safe?
  • 0.5 max. 3.0 max. Polyacrylic acid/sodium polyacrylate (PAA, PAAS) is a harmful material. Avoid contact with skin and eyes. Avoid breathing vapor. Keep container closed when not in use.
  • What is a carbomer code for polyacrylic acid (PAA)?
  • Carbomer codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer. For many applications PAAs are used in form of alkali metal or amonium salts e.g. sodium polyacrylate. Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC.
