Polysulfone (PSU)

Polysulfone (PSU) is an amorphous high-performance thermoplastic that belongs to the group of high-temperature resistant plastics.

It is applied in electrical engineering, electronics, vehicle, and mechanical engineering, for household appliances and in medical technology in cases where high heat-resistance coupled with transparency are necessary.

Polysulfone has a surface energy of 42.1 mN/m without plasma treatment. This can be greatly increased by plasma pretreatment, so that the wettability increases for a better adhesion.
