PA66 A3WG6 LS BK23189 机械强度较高

 PA66 A3WG6 LS BK23189性能：PA66 聚酰胺66或尼龙66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。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。玻璃就是最常见的添加剂，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。 PA66对许多溶剂具有抗溶性，但对酸和其它一些氯化剂的抵抗力较弱。
