Polyacrylic Acid CAS:9003-01-4

Polyacrylic acid (PAA), CAS number 9003-01-4, is a colorless to light yellow viscous liquid or solid powder. It is an important water-soluble polymer with no fixed molecular formula (the repeating unit is C₃H₄O₂). It possesses excellent water solubility, water absorption, chelating properties, and dispersibility, and is widely used in water treatment, daily chemicals, food, and industrial fields, making it a versatile polymer material.

- Water Treatment: Used as a scale inhibitor and dispersant, suitable for industrial circulating water, boiler water, and wastewater treatment. It effectively prevents the formation of scale such as calcium carbonate and calcium sulfate, disperses impurities in water, and improves water treatment efficiency.

- Daily Chemicals: Used in washing products such as shampoos, shower gels, and laundry detergents as a dispersant and chelating agent to enhance cleaning power and prevent dirt redeposition; in skincare products, it acts as a thickener and moisturizer, improving product texture and moisturizing effect.

- Food Industry: Used as a food additive (dispersant, stabilizer), added to fruit juices, beverages, dairy products, soy products, etc., to prevent particle sedimentation and improve product uniformity. It must comply with national standard limits.

- Other Fields: Used in coatings and adhesives as a thickener and stabilizer, improving product adhesion and storage stability; it can also be used as a soil conditioner and papermaking additive to optimize the performance of related products.
