Syensqo (Solvay Specialty Polymers) Radel® R-5900 MR Polyphenylsulfone (PPSU)  (discontinued **)
Categories: Polymer; Thermoplastic; Polyphenylsulfone (PPSU)

Material Notes: Radel R-5900 MR polyphenylsulfone (PPSU) offers medium melt viscosities for long flow lengths and greater injection molding ease. It also provides exceptional hydrolytic stability and toughness. It offers high deflection temperature and outstanding resistance to environmental stress cracking. The resin is inherently flame retardant and has excellent thermal stability and good electrical properties. Radel R-5900 MR is an internally lubricated grade, which offers enhanced mold release. This feature yields the benefits of shorter cycle times and lower injection pressures. Radel R-5900 MR is particularly well suited for applications where design constraints dictate thin walls, tight tolerances and minimal draft angles. - Natural/Transparent: Radel R-5900 NT MR
