Ascend Performance Materials Vydyne® 75HB NT0679 Nylon 66, Extrusion Grade (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Nylon (Polyamide PA); Nylon 66 (PA66); Nylon 66, Extruded; Nylon 66, Film
Material Notes:	75HB NT0679 is a PA66-based copolymer that features high melt strength with ideal shear thinning behavior, high tensile strength, ductility, and improved clarity making it ideal for blown and cast film applications. Having a melt temperature between PA6 and PA66, it is a preferred material of choice compared to physical blends of PA6 and PA66 due to the ability to process at lower temperatures and produce a homogenous film resulting in uniform melting behavior, high gloss, and clarity. 75HB also allows for improved process flexibility due to its slower crystallization rate versus PA66 homopolymers.
