Material Notes:
Vydyne® R228 is a 40% mineral-reinforced PA66 resin formulated for improved impact strength. Available in black, it is an injection-molding grade formulated to retain the inherent processing advantages of unreinforced PA66 while enhancing rigidity, strength and heat resistance. Vydyne R228 maintains the chemical resistance typical of PA66 to a wide variety of chemicals, gasoline, oils, greases and solvents. Vydyne R228 resin utilized a unique mineral-reinforced PA66 system developed by Ascend Performance Materials 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 impendent 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 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 R228 resin offers more uniform molded part strength and performance, as well as wider latitude in part design. Vydyne R228 resin is a workhorse of Ascend Performance Materials’ full line of mineral-reinforced PA66 resins, providing the best overall balance of properties. Vydyne R228 is heat stabilized and designed to provide increased ductility improvement results in tougher, more impact-resistant molded parts. The reduction in melt viscosity enhances overall ease of injection-molding, resulting in minor reduction in tensile strength, modulus and heat distortion temperature. Parts manufacture from Vydyne R228 have successfully withstood paint bake oven cycles without significant loss of either dimensional stability or part properties.Availability:Asia PacificEuropeNorth AmericaFiller/Reinforcement:Mineral, 40% Filler by WeightAdditive:Heat Stabilizer Features:DuctileGasoline ResistanceGood Chemical ResistanceGood Impact ResistanceGood StrengthGood ToughnessGrease ResistantHeat StabilizedHigh Heat ResistanceHigh RigidityOil ResistantSolvent ResistantUses:Automotive Exterior PartsAutomotive Under the Hood CamsGearsHousingsIndustrial ApplicationsPower/Other ToolsAppearance: BlackForms: PelletsProcessing Method: Injection MoldingInformation provided by Ascend Performance Materials.
