介绍:
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。

You are on probation!’ shrieked Professor Umbridge, and Snape looked back at her, his eyebrows slightly raised. ‘You arc being deliberately unhelpful! I expected better, Lucius Malfoy always speaks most highly of you! Now get out of my office!’
Snape gave her an ironic bow and turned to leave. Harry knew his last chance of letting the Order know what
