Rubber Sealing for Medical Applications

Medical Grade Elastomers: Understanding the Basics

Definition and Testing Protocols

Medical grade rubbers are a specialized group of compounds typically tested to FDA USP Class VI standards and ISO 10993 test protocols. These rigorous testing procedures ensure the safety and biocompatibility of materials used in medical applications.

FDA Rubber vs. Medical Grade Rubber

  • FDA Rubber typically refers to food contact rubber complying with FDA 21 CFR 177.2600
    • Specifies allowable ingredients in rubber formulations
    • Requires extraction testing in water and oil
  • Medical Grade Rubber meets more stringent biocompatibility and safety standards for medical use
