Polysulfone (PSU) Precision Machining

Facts About Polysulfone PSU

Polysulfone is best known for its high temperature resistance, hydrolytic stability, and excellent machinability. These qualities have given Polysulfone the ability to replace metals, glass and ceramics which allows the consumer to use a lighter weight material without sacrificing strength.

Polysulfone possesses good resistance to a wide variety of aggressive environmental conditions. Polysulfone is also resistant to aqueous mineral acids, alkali, and salt solutions. The material’s resistance to detergents and hydrocarbon oils is also good, even at elevated temperatures under moderate levels of stress. Polysulfone also exhibits exceptional steam resistance, including exposure to high temperature and pressure conditions. Its resistance to radiation is the highest known among plastics.

Polysulfones long term resistance to environmental stress cracking has opened up new application areas including chemical processing equipment, food processing, gas scrubbing and pollution control devices, filtration equipment, and parts involving contact with highly caustic environments.

Key Applications of Polysulfone

Medical trays, surgical instruments, lab equipment and respirators are some of the applications that polysulfone excels in. This material is typically chosen when polycarbonate and other less expensive counterparts are not chemically sound enough for the desired application. Polysulfone is also commonly used in the manufacturing of selectively permeable membranes such as the ones used in hemodialysis.
