Properties and Uses of Aromatic Polyether Sulfones

In general, properties of polyether sulfones are similar to those of polycarbonates, but they can be used at higher temperatures. Figure 1.1 shows the maximum use temperature for several thermoplastics.

Aromatic polyether sulfones can be extruded into thin films and foil and injection molded into various objects that need high-temperature stability.
