Introduction
Polyethersulfone (PES) is synthesized from Bisphenol S and 4.4′-Dichlorodiphenyl Sulfone. PES offers excellent performance in chemical resistance, heat stability (heat deflection temperature of 195℃), and impact strength. With the above characteristics, PES is a kind of high performance engineering thermoplastic resin.
