Polyphenylsulfone


Polyphenylsulfone is a type of high performance polymer usually consisting of aromatic rings linked by sulfone groups.

Production

The commercially important polysulfones are prepared by condensation of 4,4'-bissulfone with various bisphenols. Two bisphenols for this application are bisphenol A and 4,4'-bissulfone.

Applications

These are moldable plastics often used in rapid prototyping and rapid manufacturing applications. Polyphenylsulfone is a heat and chemical-resistant suited for automotive, aerospace, and plumbing applications. Polyphenylsulfone has no melting point, reflecting its amorphous nature, and offers tensile strength up to 55 MPa. 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.
