Polyacrylic Acid Product Description
Polyacrylic Acid (PAA) is a synthetic polymer derived from acrylic acid. It is a water-soluble polymer that exhibits excellent thickening, dispersing, and stabilizing properties. PAA is widely used in various industries due to its ability to form gels and its high viscosity at low concentrations. The polymer is typically available in both powder and liquid forms, making it versatile for different applications. Its unique chemical structure allows it to interact with water and other substances, making it an essential ingredient in many formulations.
Key Features:
- High Viscosity: Provides thickening properties in formulations.
- Water Solubility: Easily dissolves in water, making it suitable for aqueous systems.
- Biocompatibility: Safe for use in personal care and pharmaceutical applications.
- Stabilizing Agent: Helps to stabilize emulsions and suspensions.
Common Uses:
- Personal Care Products: Used in lotions, creams, and gels for its thickening and stabilizing properties.
- Pharmaceuticals: Acts as a binder and thickener in various drug formulations.
- Agriculture: Utilized in fertilizers and soil conditioners to improve water retention.
- Adhesives and Sealants: Enhances the viscosity and performance of adhesive formulations.
- Paints and Coatings: Serves as a thickener and stabilizer in water-based paints.
