PPSU Properties

PPSU is the acronym for Polyphenylsulfone. Also known as PPSF, PPSU is part of Sulfone polymers, which are high performance polymer exhibiting very attractive properties such as high temperature performance, good chemical resistance, outstanding toughness, excellent colorability and very good dimensional stability. As the other sulfone polymers, PPSU is an amorphous polymer and displays therefore very good creep resistance, isotropic thermal and mechanical properties (if non reinforced) and transparency properties. PPSU is used in various applications including plumbing, food services, medical, aerospace, wire & cable, etc.

DYCO use Radel grade PPSU manufacture the industrial leading brand Solvay, most of Radel® PPSU compounds comply with U.S. FDA and European Union (EU 10/2011 and 1183/2012) regulations for use as components of articles intended for repeat use in contact with all types of foods.

DYCO use Radel® PPSU displays a very good chemical resistance to many chemicals including: aqueous systems, caustics, inorganic acids, aliphatic hydrocarbons, detergents and soaps and certain alcohols.

Radel®R-5100 is an opaque, general purpose polyphenylsulfone (PPSU) for injection molding, that offers exceptional hydrolytic stability, and toughness superior to other commercially-available, high-temperature engineering resins. This resin also offers a high deflection temperature and outstanding resistance to environmental stress cracking. Radel®polymers are inherently flame retardant, provide excellent thermal stability and possess good electrical properties.
