Polyethersulfone (PES) is an amorphous plastic (super engineering plastic) with high heat resistance of Tg 225 °C.
In addition to high heat resistance, it has excellent dimensional stability, high fluidity, flame retardancy, and other characteristics and is used in a wide range of industrial fields such as housings for electrical and electronic components, commercial tableware, and automobile parts.
