Ascend Performance Materials Vydyne® R220/R228 Nylon 66, 40% Mineral Reinforced, Conditioned (2.5% Moisture)

Vydyne® R220 is a 40% mineral reinforced Nylon 66 resin formulated for improved impact strength. Also available in black as R228. It is an injection molding grade formulated to retain the inherent processing advantages of unreinforced Nylon 66 while enhancing rigidity, strength, and heat resistance. Vydyne R220/R228 maintains the chemical resistance typical of nylon to a wide variety of chemicals, gasoline, oils, greases, and solvents. Vydyne R220/R228 resins utilize a unique mineral reinforced nylon system developed by Solutia to satisfy the market need for a high-rigidity thermoplastic as an alternative to certain metals. This mineral system provides two key features: (1) isotropic behavior — property development in molded parts is usually independent of flow direction. (2) a reduction in the tendency to develop sink marks in heavy cross sections such as molded-in bosses and ribs. While not sink free, parts made from Vydyne R220/R228 can often permit boss and rib design or wall cross section changes that would not be tolerable in other unreinforced thermoplastic materials. Thus Vydyne R220/R228 resins offer more uniform molded part strength and performance as well as wider latitude in part design. Vydyne R220/R228 are heat stabilized and designed to provide increased ductility and reduced melt viscosity vs. unreinforced materials. This ductility improvement results in tougher, more impact-resistant molded parts. The reduction in melt viscosity enhances overall ease of injection molding, resulting in minor reductions in tensile strength, modulus, and heat distortion temperature. Parts from Vydyne R220/R228 have successfully withstood paint bake oven cycles without significant loss of either dimensional stability or part properties.
