Used in aerospace and automotive industries for lightweight, high-strength components due to excellent thermal stability and resistance to chemicals and wear. Commonly found in seals, bearings, and compressor parts. Widely used in medical implants such as spinal devices and trauma fixation because it is biocompatible and radiolucent. Applied in oil and gas equipment for downhole tools and seals that withstand harsh environments. Also used in semiconductor manufacturing and electrical insulation where high-performance polymers are required.
