Used in aerospace and automotive industries for lightweight, high-strength components due to excellent mechanical and thermal stability. Commonly found in seals, bearings, and compressor parts that must endure high temperatures and harsh chemicals. Widely adopted in medical implants, such as spinal devices, because it is radiolucent and biocompatible. Employed in semiconductor manufacturing equipment for its low outgassing and resistance to cleaning agents. Also used in oil and gas downhole tools where long-term performance under extreme pressure and temperature is required.
