PPSU (Polyphenylsulfone)

PPSU (Polyphenylsulfone) is an amorphous, high-performance thermoplastic belonging to the polyarylsulfone group. The material is characterized by high temperature resistance, high toughness, and good chemical and hydrolysis resistance. In addition, PPSU has very low water absorption and high dimensional stability.

Due to its stable property profile, PPSU is used for technically demanding components that must function reliably under continuous thermal stress and in contact with hot water or steam.
