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
