Ascend Performance Materials Vydyne® 840F Nylon 66, Extrusion Grade (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Nylon (Polyamide PA); Nylon 66 (PA66); Nylon 66, Extruded; Nylon 66, Film
Material Notes:	Vydyne 840F is a PA66-based copolymer that features high melt strength, shear thinning behavior, high tensile strength, ductility, and slow crystallinity that matches crystallization temperatures/rates very close to that of ethylenes. The combination of properties exhibited by Vydyne 840F make it a good candidate for a number of applications such as numerous film uses, sheeting, and monofilament. The slow crystallization behavior coupled with the melting point ~ 215-220°C and great mechanical properties makes this material extremely useful for outside layers or internal layers of the multilayer film. This material further exhibits a very high elongation to break (> 500%) allowing for high draw ratios for thermoforming or when orienting the film.
