Sodium polyacrylate
MF: C3H4O2
MW: 72.06
CAS: 9003-04-7
Sodium polyacrylate is white powder, odorless.
Sodium polyacrylate can be used as corrosion and scale inhibitor, water quality stabilizer, coating thickener and water retention agent, flocculant, drilling mud treatment agent, etc.
Sodium polyacrylate (PAAS) is a new type of functional polymer material and an important chemical product. The commercial form of sodium polyacrylate has a relative molecular weight ranging from a few hundred to tens of millions. Due to varying degrees of neutralization, the pH of aqueous solutions is generally between 6 and 9. Capable of ionization, with or without corrosiveness. It is easily in aqueous solutions such as calcium hydroxide and magnesium hydroxide, as the number of alkaline earth metal ions increases, it first dissolves and then precipitates.
Low molecular weight (500-5000): scale inhibition, dispersion, and corrosion inhibition effects, mainly used in oilfield chemicals and viscosity reducing agents for drilling; Water treatment industry scale remover and anti scale agent; Paper pigment dispersant; Textile sizing agents and dispersants; Used as a washing aid in the washing industry; Paint dispersant; Ceramic additives, high-efficiency cement water reducing agents; Quenchants for metal materials, etc.
Medium molecular weight (100000-10 million): thickener, water retaining agent;
High molecular weight (>10 million): thickener, flocculant.
