PES (polyethersulfone) is an amorphous polymer with excellent comprehensive properties. It combines good chemical resistance with a high heat deflection temperature of 205 °C(ISO 75). And PES resin is inherently flame retardant for application of electronic components and testing devices. Its chemical resistance and mechanical properties are better than PSU (polysulfone). Because of its good hydrophilic and lipophilic properties, PES can be used for non-stick pan coatings. PES has obtained ISO10993, NSF, EU10/2011, IATF16949, REACH and other certifications. As a high-performance material, PES is widely used in food containers, medical appliances, paints, non-stick coatings, insulating electrical and electronic parts, hemodialysis membranes, automotive fog lamps and many other fields.
