Polyacrylic Acid(PAA) CAS 9003-01-4
Sinocheme is a major Polyacrylic acid & PAA supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Polyacrylic acid & PAA.
Polyacrylic Acid (PAA) is non-toxic, easily soluble in water, and can operate under alkaline and medium concentration conditions without scaling.
- PAA can disperse microcrystals or sediment of salts such as calcium carbonate and calcium sulfate in water without precipitation, thereby achieving the purpose of scale inhibition;
- PAA is a commonly used dispersant, in addition to being used as a scale inhibitor dispersant in circulating cooling water systems such as power plants, chemical plants, fertilizer plants, refineries and air conditioning systems.
- PAA is also widely used in papermaking and textile, printing and dyeing, ceramics, coatings, building materials and other industries.
Polyacrylic acid Description
Name: Polyacrylic acid (PAA)
Synonyms: Acrylic Acid Polymer / Acrylic Acid Homopolymer
Molecular Formula: (C3H4O2)x
CAS NO.: 9003-01-4
Density: 1.09 (30% aq.)
Boiling point: 116ºC
Melting point: 106ºC
Flashing point: 61.6ºC
Appearance: Colorless or light yellow liquid
Solubility: Soluble in water
Properties:
1. Polyacrylic acid is innoxious. It is soluble in water. People use this PAA polymer in 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.
2. It is a scale inhibitor and dispersant for circulating cool water systems, papermaking, weaving, dyeing, ceramics, painting, etc.
3. Polyacrylates can be made into highly absorbent plastics. Polyacrylic acid plastic has the advantages of strong water absorption capacity, no toxicity, and no pungent odor; it can be used in baby diapers.
4. The maximum water absorption of polyacrylate can reach 1200 times. The copolymer of methyl methacrylate and vinyl acetate is hydrolyzed under pressure and converted into heavy and light groups, which can be used to prepare super-absorbent plastics. It has high water absorption and water retention.
Usage: People can use polyacrylic acid to circulate cool water systems in power plants as a scale inhibitor and dispersant, also in iron & steel factories, chemical fertilizer plants, refineries, and air conditioning systems. Its dosage should be by water quality and equipment materials. When workers use PAA polymer alone, 1~15 mg/L is preferred.
Package: 200L plastic drum, IBC (1000L). Also as customers’ requirements.
Storage: Sealed at room temperature, away from light, ventilated and dry place
Safety Protection: Acidity, avoid contact with eyes and skin. Once contacted, flush with water.

Polyacrylic acid Applications
1. People use polyacrylic acid and its derivatives in throw-away baby diapers. Also in ion exchange resins, adhesives, and cleaning agents.
2. By the way, cleaning agents are copolymers of acrylic acid in many cases. Engineers also use acrylic acid copolymers in zeolites and phosphates in washing powder products.
3. 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.
4. To develop polymeric matrices that allow a controlled delivery rate of active substances. The latest research aimed towards the following clarification.
5. The conformational changes of the polymeric gel during neutralization, light irradiation, and embedment of gold nanoparticles.
6. Meanwhile, the US Food and Drug Administration authorized using SAPs in packaging with indirect food contact.
We offer competitive Polyacrylic acid & PAA price, and exclusive discounts for large quantities, helping you effectively reduce procurement costs.
