Used in aerospace and automotive industries for lightweight, high-strength components due to excellent thermal stability and resistance to chemicals. Commonly found in seals, bearings, and electrical insulation where performance under extreme conditions is required. Widely adopted in medical implants because of its biocompatibility, durability, and ability to withstand repeated sterilization. Also used in oil and gas equipment for parts exposed to high pressure and corrosive environments. Increasingly used in 3D printing for functional prototypes and end-use parts requiring high performance.
