Polyacrylic Acid, PAA Polymer
Polyacrylic acid is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. The polyacrylic acid solution can disperse the microcrystals or micro sand of calcium carbonate, calcium phosphate, and calcium sulfate.
Polyacrylic acid is used as a scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

30%, 40% ,60% Polyacrylic Acid are supplied too.
Polyacrylic acid can be used as a scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries, and air conditioning systems. Dosage should be in accordance with water quality and equipment materials. When this PAA polymer used alone, 1-15mg/L is preferred.
Polyacrylic acid and the derivatives are widely-used inside throw-away baby diapers, ion exchange resins, adhesives, and also cleaning agents.
Cleaning agents in many cases are copolymers of acrylic acid which can be used in both zeolites and phosphates in washing powder products.
PAA polymer may inactivate the antiseptic chlorhexidine gluconate. The neutralized polyacrylic acid gels are usually appropriate to acquire biocompatible matrices for healthcare purposes. Such as skin gels for skincare or skin disease treatment products.
For the development of polymeric matrices that allows a controlled delivery rate of active substances, the latest research aimed towards the clarification of the conformational changes of the polymeric gel during neutralization, light irradiation, and embedment of gold nanoparticles. The US Food and Drug Administration authorized the use of SAPs in packaging with indirect food contact.
Package and Storage:
200L plastic drum, IBC (1000L). Also as customers’ requirement. Storage for one year in shady room and dry place.
Acidity, avoid contact with eye and skin. Once contacted, flush with water.
Frequent Asked Questions
What is polyacrylic acid used for?
Polyacrylic acid is a low molecular weight acrylic acid monomer. It is usually used in combination with organic phosphonates and organophosphonates, polyphosphates, and has a good synergistic effect. It has excellent dispersing effect on calcium phosphonate and iron oxide in water.
PAA polymer can be run under alkaline and high concentration conditions without fouling. Polyacrylic acid does not pollute the environment when it is discharged.
Polyacrylic acid is non-toxic, soluble in water, and can be operated under alkaline and medium concentration conditions without scaling. Polyacrylic acid is a commonly used dispersant widely used in paper and textile, printing and dyeing, ceramics, coatings and other industries. PAA polymer is used in the slurry for sizing.
Is polyacrylic acid biodegradable?
The polyacrylic polymer solution has two parts of a monomer (easy to rapidly degrade) and a polymer (which is not easily degraded rapidly). The monomer will be explained first, and the polymer is degraded slowly. However, over time, PAA polymer will be fully explained. The specific experimental process will be explained in the following article.
What is polyacrylic acid soluble in?
Polyacrylic acid should dissolve well in polar solvents. For example, water, methanol, ethanol, and DMF are all acceptable. The carboxyl group is a hydrophilic group.
