Polyacrylic Acid
Polyacrylic Acid, a water-soluble homopolymer of acrylic acid, forms clear, viscous solutions or gels upon neutralization, with molecular weights ranging from 2,000 to 5,000,000 Da for customizable rheology. This anionic polyelectrolyte expands in aqueous media due to electrostatic repulsion, providing thickening and dispersing functions in formulations, as detailed in PubChem compound summaries for industrial-grade variants.
Polyacrylic Acid
Deployed in household cleaners as viscosity modifiers; in water treatment for flocculant enhancement; in agriculture as hydrogel soil amendments; in pharma gels for topical delivery; and in battery electrolytes for ion conductivity improvement in energy storage systems.
Acidic forms corrosive to eyes and skin; neutralized versions milder but dust inhalation may cause pulmonary irritation. Low biodegradability raises environmental concerns per EFSA; neutralize spills promptly and use enclosed transfer systems with chemical-resistant gloves to comply with GHS classifications.
Shipped in 200 kg intermediate bulk containers with acid-proof valves for bulk handling. Store horizontally in corrosion-protected racking, monitored for leaks in dedicated polymer areas.
