NIPAAm

polymer

NIPAAm (N-isopropylacrylamide) is a synthetic polymer known for its thermally responsive behavior, exhibiting a sharp phase transition in aqueous solutions near body temperature. It is widely used in biomedical, pharmaceutical, and biotechnology applications where reversible swelling and controlled release are advantageous, including drug delivery systems, cell culture scaffolds, and smart hydrogels that respond to temperature changes. Engineers select NIPAAm-based materials when they require stimuli-responsive functionality—enabling on-demand release of therapeutics or reversible mechanical changes—making it particularly valuable in biomedical devices where conventional static polymers are inadequate.

Regulatory Screening

Environmental

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.
