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 withstand high temperatures and harsh chemicals. Widely adopted in medical implants, such as spinal devices, because it is biocompatible and radiolucent, allowing clear imaging. Employed in oil and gas equipment for its resistance to corrosion and high-pressure environments. Also used in semiconductor manufacturing and electrical insulation where purity and performance under heat are critical.
