Applications
PPSFs are moldable plastic often used in rapid prototyping and rapid manufacturing (direct digital manufacturing) applications. Polyphenylsulfones are heat and chemical-resistant suited for automotive, aerospace, feeding bottle and plumbing applications, Polyphenylsulfone has no melting point, reflecting its amorphous nature, and offers tensile strength up to 55 MPa (8000 psi). Its commercial name is Radel. In plumbing applications, polyphenylsulfone fittings have been found to sometimes form cracks prematurely or to experience failure when improperly installed using non-manufacturer approved installation methods or systems.
