Comparison of linear and branched Polyphenylsulfone PPSU in film and granular form

A linear and a branched polymer were characterized with respect to its mechanical properties and structure. The measuring procedure can be applied in a fast and easy way. The measurements were performed using an Anton Paar Rheometer MCR with the Convection Temperature Device.

1.1 Sample

Polyphenylsulfone PPSU

Polyphenylsulfone (PPSF or PPSU) is a type of moldable plastic often used in rapid prototyping and rapid manufacturing (direct digital manufacturing) applications. Polyphenylsulfone is a heat- and chemical-resistant material. It is typically used in automotive and aerospace applications. It has virtually no melting point, due to its amorphous nature. It offers high tensile strength. Its commercial name is Radel®R.
