POLYACRYLIC ACID

Polyacrylic Acid 
PAA

Polyacrylic acid is used for water treatment as dispersant and sludge conditioner

Aquatreat AR 4

Additional information
Polyacrylic acid is suitable for use in a number of applications where dispersion, suspension, and sequestration characteristics are required. 
Polyacrylic acid is a hydrophilic colloid similar in properties to many water soluble gums.
The rate of resolubilization of films of Polyacrylic acid can be controlled by treatment with a 10% solution of various mineral acids or multivalent cations.

CAS No. 9003-01-4

Structural Formula:
CCCOOH*H*HHn

Properties:
PAA is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. PAA can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

Polyacrylic Acid, PAA Polymer
Properties:
Polyacrylic acid is innoxious. It is soluble in water. People use this PAA polymer in situations of alkaline and high concentration without scale sediment. The PAA polymer solution can disperse the microcrystals or micro sand of calcium carbonate, calcium phosphate, and calcium sulfate.

It is used as a scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramics, painting, etc.

Usage:
As a scale inhibitor and dispersant, people can use polyacrylic acid in circulating cool water systems in power plants. Also in iron & steel factories, chemical fertilizer plants, refineries, and air conditioning systems. Its dosage should be in accordance with water quality and equipment materials. When workers use PAA polymer alone, 1-15 mg/L is preferred.

Applications:
People use polyacrylic acid and its derivatives inside throw-away baby diapers. Also in ion exchange resins, adhesives, and cleaning agents widely.

By the way, cleaning agents are copolymers of acrylic acid in many cases. Engineers also use acrylic acid copolymers in both zeolites and phosphates in washing powder products.

This PAA polymer may inactivate the antiseptic chlorhexidine gluconate. And the neutralized polyacrylic acid gels are usually appropriate to acquire biocompatible matrices. That is for healthcare purposes. Such as skin gels for skincare or skin disease treatment products.

For the development of polymeric matrices that allow a controlled delivery rate of active substances. The latest research aimed towards the following clarification.

The conformational changes of the polymeric gel during neutralization, light irradiation, and embedment of gold nanoparticles.

Meanwhile, the US Food and Drug Administration authorized the use of SAPs in packaging with indirect food contact.

Applications
Booster for fabric detergents
Laundry solutions and detergents
Water treatment flocculation
