The global polyethersulfone (PES) market value reached US$ 368.4 million in 2022 and is expected to reach US$ 658.5 million by 2031, growing at a CAGR of approximately 7.6 % during the forecast period 2024-2031.
PES is a high-performance thermoplastic polymer known for its excellent thermal stability, chemical resistance, mechanical strength and dimensional stability. These properties make PES well-suited for demanding applications such as water- and air-filtration membranes, medical devices (e.g., dialysis filters), electronics components, automotive parts and industrial equipment.
