Vydyne® 75HB NT0679

About
Vydyne 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. Further, 75HB also allows for improved process flexibility due to its slower crystallization rate versus PA66 homopolymers.&&
