Selection guide

Medical-grade plastics

Medical-grade polymers combine biocompatibility (ISO 10993 / USP Class VI), sterilization tolerance (autoclave, gamma, EtO), and manufacturability. Medical PEEK, PC, PP, silicone, TPU and specific PSU/PPSU grades dominate the category.

What to look for

  • ISO 10993 or USP Class VI qualified grades available
  • Withstands the intended sterilization method
  • Documented supply chain and change control
