Sodium polyvinylphosphonate (CAS 118632-18-1), the sodium salt of poly(vinylphosphonic acid), is a water-soluble polymeric sequestrant.

Where is Phosphonic acid, (1-methylethenyl)-, homopolymer, sodium salt used?

• Water treatment: controls calcium carbonate and calcium phosphate scale in cooling towers, boilers and recirculating systems, particularly at elevated temperatures and high hardness levels
• Industrial and institutional cleaning: sequesters hardness ions, improving detergent performance in hard water
• Textile processing: prevents metal ion interference during dyeing and finishing, protecting colour consistency and fabric quality
• Paper manufacturing: controls mineral deposits in process water
• It functions by binding metal ions and inhibiting scale formation.

Commercial specifications

• Active content typically 30% to 50%
• Drums and IBC totes
