RT-duroid® laminates, based on polytetrafluoroethylene (PTFE) reinforced with glass microfibers or ceramics, are commonly used in high-frequency applications. When exposed to nuclear radiation, these materials exhibit specific changes in physical, electrical, and mechanical properties.

RT-duroid® laminates are high-performance PTFE-based composite materials manufactured by Rogers Corporation. These laminates are primarily used in RF, microwave, and high-frequency applications due to their exceptional dielectric properties, thermal stability, and chemical resistance.
