Vydyne® 75HB NT0679是一种PA66基共聚物,具有高熔融强度和理想的剪切减薄行为、高拉伸强度、延展性和提高透明度,使其成为吹塑和铸膜应用的理想选择。熔融温度介于PA6和PA66之间,与PA6和PA66的物理混合物相比,它是首选材料,因为它能够在较低的温度下加工并产生均匀的薄膜,从而产生均匀的熔融行为、高光泽和清晰度。此外,与PA66均聚物相比,75HB的结晶速度较慢,因此可提高工艺灵活性。 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. |
