poly(2-hydroxyethyl methacrylate)
polymerPoly(2-hydroxyethyl methacrylate), commonly known as PHEMA, is a synthetic hydrophilic polymer formed from methacrylate monomers bearing hydroxyl side groups. This material is valued in biomedical applications for its hydrogel-forming capability, biocompatibility, and tunable water content, making it particularly suited for implant coatings, soft-tissue contact devices, and controlled-release matrices. Engineers select PHEMA over alternative polymers when applications demand a balance of mechanical stability with moisture absorption and biological tolerance.

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.
