Technical Datasheet | Supplied by Syensqo

Radel® R-5900 MR by Syensqo is a lubricated, flame retardant polyphenylsulfone (PPSU) grade. Exhibits good flow, good mold release, good chemical resistance, good electrical properties, high environmental stress crack resistance, and high heat resistance. Offers medium melt viscosity, resistance to acids & bases, good thermal stability, hydrolytic stability, steam sterilizability and ultra-high toughness. Radel® R-5900 MR is suitable for processing by injection molding and extrusion. Recommended applications include appliances, consumer applications, and food contact applications. It is particularly suitable for applications where design constraints dictate thin walls, tight tolerances, and minimal draft angles.
