polysulfone

polysulfone

      any of a class of resinous organic chemical compounds belonging to the family of polymers in which the main structural chain most commonly consists of benzene rings linked together by sulfonyl (−SO2−), ether (−O−), and isopropylidene (−C(CH3)2−) groups.

      The polysulfone resins, introduced in the 1960s, are tough, strong, stiff, and resistant to decomposition by heat or chemical attack. They retain their mechanical properties over a wide temperature range (−70° to 150° C, or about −95° to 300° F) and are used as wire coatings, for fabricating household and plumbing items, and for automotive parts.
