Polysulfone (PSU) is an amorphous, high temperature, high performance polymer based on phenylene units linked by three different chemical groups: isopropylidene, ether, and sulfone. Key characteristics of PSU are its excellent thermal stability, high toughness and strength, good environmental stress crack resistance, high temperature resistance, transparency and low creep. PSU can be processed by most standard processing methods. Typical applications include automotive fuses, headlight bezels, plumbing fittings, home appliances, non-stick cookware, airplane dishes, pump impellers, filter membranes, and high temperature visors.
