Poly(potassium acrylate)

polymer

Poly(potassium acrylate) is a water-soluble synthetic polymer derived from acrylic acid, featuring ionic potassium salt groups along its backbone that confer hydrophilic character and pH responsiveness. This material is primarily encountered in research and specialized industrial applications where its hygroscopic nature, ionic functionality, and ability to form hydrogels are exploited for moisture management, ion exchange, or biocompatible systems. Engineers select poly(potassium acrylate) over conventional acrylates when they need tunable swelling behavior, salt responsiveness, or applications requiring controlled water uptake—though its water sensitivity and ionic nature limit its use to non-structural roles and moisture-protected environments.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
