O PEEK apresenta módulo elástico similar ao do osso, otimizando a transmissão de forças quando implantado no osso esponjoso ou osso cortical. Estas características tornam o PEEK extremamente biocompatível, tanto do ponto de vista químico como do ponto de vista de comportamento mecânico desejado (biofuncionalidade ou biocompatibilidade de massa).
O PEEK é um material não magnético, sendo totalmente compatível com ambiente de ressonância magnética (ASTM F 2503-05, F2026, definition 3.1.7), tanto do ponto de vista de segurança como pela inexistência de artefatos de imagem ao exame.
