Vydyne® 840F是一种PA66基共聚物,具有高熔融强度、剪切稀化行为、高拉伸强度、延展性和慢结晶性,与乙烯的结晶温度/速率非常接近。Vydyne® 840F所展示的性能组合使其成为许多应用的很好的候选者,例如许多薄膜用途、片材和单丝。缓慢的结晶行为加上~215-220°C的熔点和良好的机械性能,使该材料非常适用于多层膜的外层或内层。这种材料还表现出非常高的断裂延伸率(>500%),允许热成型或薄膜定向时的高拉伸比。 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. |
