FAQ
What's the difference between USP Class VI and ISO 10993 testing for medical plastics?
USP Class VI is a basic biological reactivity test using extracts, while ISO 10993 is a comprehensive series of biocompatibility tests including cytotoxicity, sensitization, and irritation. ISO 10993 is preferred for medical devices as it's more rigorous and internationally recognized. Many medical-grade resins carry both certifications.
How do I handle change notifications from my medical resin supplier?
Establish a formal change notification process with your supplier covering manufacturing site changes, raw material sources, and formulation modifications. Require 90-day advance notice minimum and assess impact on your regulatory filings. Some changes may require re-validation or regulatory submission updates.
Which sterilization method is most compatible with medical plastics?
Ethylene oxide (EtO) is generally most compatible across different plastic types, followed by gamma irradiation. Steam sterilization (autoclave) is limited to higher-temperature resistant materials like PEEK and some polypropylenes. Always validate your specific resin grade with your chosen sterilization cycle.
What documentation should I expect from a medical-grade resin supplier?
Require certificates of analysis, biocompatibility test reports, FDA DMF numbers (if applicable), manufacturing site certifications, and traceability records. Suppliers like Colorado Sun Inc provide comprehensive documentation packages to support your regulatory compliance needs.
How do I select between different medical-grade polycarbonate options?
Consider your sterilization requirements, optical clarity needs, and chemical exposure. Standard medical PC works for most applications, while specialized grades offer enhanced stress crack resistance or improved gamma stability. Flow characteristics also vary for different part geometries and processing requirements.
