| Polyethersulfone (PES) is a amorphous high heat resistance engineering polymer. It is transparency, outstanding hydrolysis resistance, inherent flame retardancy, excellent resistance to a broad range of chemicals and low smoke, can withstand high temperatures under load, and provides stable performances under extreme temperature changes. This overall outstanding performance material can be used in electronic/electrical, food and tableware, military, automotive, aerospace, and medical fields. |
