Acrylic Acid Polymer Acrylic Acid Homopolymer Acrylic Acid Resin

Description

Poly acrylic acid is hygroscopic, brittle and colorless in nature. 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.

Application

PAA is indeed used as an antiscalant. It functions primarily to inhibit scaling in various water treatment processes, particularly in reverse osmosis (RO) and nanofiltration (NF) systems. Here are some key points regarding its application as an antiscalant: PAA are also used as thickeners, dispersing, suspending and emulsifying agents in pharmaceuticals, cosmetics and paints.
