化学和物理特性:
PA66在聚酰胺材料中有较高的熔点。它是一种半晶体-晶体材料。PA66在较高温度也能保持较强的强度和刚度。PA66在成型后仍然具有吸湿性,其程度主要取决于材料的组成、壁厚以及环境条件。在产品设计时,一定要考虑吸湿性对几何稳定性的影响。
为了提高PA66的机械特性,经常加入各种各样的改性剂。玻璃就是**常见的添加剂,有时为了提高抗冲击性还加入合成橡胶,如EPDM和SBR等。
PA66的粘性较低,因此流动性很好(但不如PA6)。这个性质可以用来加工很薄的元件。它的粘度对温度变化很敏感。PA66的收缩率在1%~2%之间,加入玻璃纤维添加剂可以将收缩率降低到0.2%~1%
。收缩率在流程方向和与流程方向相垂直方向上的相异是较大的。
