Terminal applicationsmainly in machinery, electronics, electrical, instrumentation,automotive components, railway, home appliances, communications,textile, oil pipe/tank and precision engineering products, etc.,EP158 also can be used for the production of film, packing, medicalequipment, sporting goods, and daily necessities and soon.
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，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。A66 Zytel 塑胶原料性能特点?PA66是PA系列中机械强度*高、应用*广的品种,因其结晶度高,故其刚性、耐热性都较高超声波可焊接低分子量经润滑可加工性良好良好的成型性能良好的电气性能流动性高耐化学性良好耐磨损性良好耐疲劳性能耐油性能耐油脂性能生产阶段快脱模性能良好等;
