Polyethersulfone is a new high-temperature engineering thermoplastic with an outstanding long-term resistance to creep at temperatures up to 150°C. It is also capable of being used continuously under load at temperatures of up to about 180°C and, in some low-stress applications, up to 200°C. ... While the sulfone group confers high-temperature performance, the ether linkage contributes toward practical processing by allowing mobility of the polymer chain when in the melt phase. ... Polyethersulfone is especially resistant to acids, alkalies, oils, greases, and aliphatic hydrocarbons and alcohols. It is attacked by ketones, esters, and some halogenated and aromatic hydrocarbons.

A urethane is formed from the reaction of an isocyanate with an alcohol. In general, polyurethanes are made using a diisocyanate, a low molecular weight diol(thermoplastic) and/or triol(cross-linked), and a polyether glycol or a polyester glycol. If the reagents are difunctional, a non cross-linked thermoplastic polyurethane will be formed; if the functionality of at least one of the reagents is greater than two, a cross-linked or three dimensional network will form. Cross-linked polyurethanes exhibit less mechanical creep than non cross-linked polyurethanes. The rubbery modulus of polyurethanes increases as the level of cross-linking is increased. Polyurethanes are diblock copolymers. They consist of hard segments(isocyanate and the chain extender rich areas) that act as physical crosslinks, and soft segments(polyether or polyester glycol rich areas).
