| 释义 |
ProductionThe commercially important polysulfones are prepared by condensation of 4,4'-bis(chlorophenyl)sulfone with various bisphenols. Two bisphenols for this application are bisphenol A (the polymer being called PSF) and 4,4'-bis(4-hydroxyphenyl)sulfone (the polymer being called PES). ApplicationsThese are moldable plastics often used in rapid prototyping and rapid manufacturing (direct digital 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,[2] and offers tensile strength up to 55 MPa (8000 psi). Its commercial name is Radel.[3] 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.[4] References1. ^El-Hibri, M.
