Radel® R-5800 is a high melt flow grade of Radel® polyphenylsulfone (PPSU). It is especially well-suited for parts requiring long flow length with thin walls. Radel® resins offer exceptional hydrolytic stability and toughness superior to other commercially-available, high-temperature engineering resins. They also offer high deflection temperatures and outstanding resistance to environmental stress cracking. Radel® polymers are inherently flame retardant, provide excellent thermal stability and possess good electrical properties. Additonal Radel® grades include a transparent injection molding grade (R-5000), an opaque, General Purpose, injection molding grade (R-5100) and a transparent, extrusion grade (R-5500). - Natural/Transparent: Radel® R-5800 NT - Additional Made-to-Order Colors Available
