EVA foam safety

Not all EVA foam is created equal. The FDA recognises EVA as a food-contact safe polymer in its higher purity grades, and the U.S. Pharmacopeia approves medical-grade EVA at the USP Class VI tier for surgical-implant applications. The safety question is therefore not "is EVA safe?" but "which grade of EVA, with which additives, certified by whom?" PopsyKosy publishes the answer to all three questions: USP Class VI medical-grade resin, no plasticizer additives, with CPSIA + independent formaldehyde + RIPT certification.
