用途 广泛应用于机械、仪器仪表、汽车部件、电子电气、铁路、家电、通讯、纺机、体育休闲用品、油管、油箱及一些精密工程制品。 电子电器：连接器、卷线轴、计时器、护盖断路器、开关壳座 汽车： 散热风扇、门把、油箱盖、进气隔栅、水箱护盖、灯座 工业零件：椅座、自行车输框、溜冰鞋底座、纺织梭、踏板、滑输     特性 1、具有优良的耐磨性、自润滑性，机械强度较高。但吸水性较大，因而尺寸稳定性较差 2、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。 3、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。 4、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      本公司长期供应塑胶原料，种类多样化，标准化，技术化，价格合理。发货准，交期准.质量有保障！本公司郑重承诺：诚信经营，质量至上，可為客户提供（物性、报价、UL报告、RoSH标准、SGS检测报告等）敬请来电咨询洽谈！详情请致电：严生（业务经理）。手机；   详细说明：But before reaching it he paused. It was not only he they sought to destroy, but the room. There was evidence of crime in the room. In that moment of keenly aroused intelligence he felt sure of it. What was to be done­ How could he save the room, and, by these means, save himself and her­ A single glance about assured him that he could not save it. The boards under his feet were hot. Glints of yellow light streaking through the shutters showed that the lower storey had already burst into flame. The room must go and with it every clue to the problem which was agitating him. Meanwhile, his eyeballs were smarting, his head growing dizzy. No longer sure of his feet, he staggered over to the wall and was about to make use of its support in his effort to reach the window, when his eyes fell on the spot from which he had peeled the paper, and he came to a sudden standstill. A bit of pink was showing under one edge of the blue.
