PA66 （聚酰胺66或尼龙66），同PA6相比，PA66更广泛应用于汽车工业、仪器壳体以及其它需要有抗冲击性和高强度要求的产品。聚酰胺树脂，英文名称为polyamide，简称PA。俗称尼龙(Nylon)，它是大分子主链重复单元中含有酰胺基团的高聚物的总称。为五大工程塑料中产量***大、品种***多、用途***广的品种。尼龙中的主要品种是尼龙6和尼龙66，占jue对主导地位， 中文名称尼龙66外文名Polyamide 66又称尼龙66缩写nylon 66CAS编号32131-17-2成分聚己二酰己二胺适用范围机械、汽车、电气装置的零件
PA66 (polyamide 66 or nylon 66), compared with PA6, is more widely used in the automotive industry, the shell of the instrument, and other products that require impact resistance and high strength. Polyamide resin, the English name is polyamide, or PA. Commonly known as Niron (Nylon), it is a general term for polymers containing macrocyclic backbone chains containing amide groups. It is a variety of five major engineering plastics which yield ***, *** and ***. The main varieties of nylon are nylon 6 and nylon 66, leading to Jue, Chinese name nylon 66 foreign name Polyamide 66, nylon 66 abbreviated nylon 66CAS 32131-17-2 component poly (two acyl) adipamine suitable for mechanical, automotive, electrical equipment parts

PA6的化学物理特性和PA66很相似，然而，它的熔点较低，而且工艺温度范围很宽。它的抗冲击性和抗溶解性比PA66要好，但吸湿性也更强。因为塑件的许多品质特性都要受到吸湿性的影响，因此使用PA6设计产品时要充分考虑这一点。为了提高PA6的机械特性，经常加入各种各样的改性剂。玻璃纤维就是***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。对于没有添加剂的产品，PA6的收缩1%到1.5%之间。加入玻璃纤维添加剂可以使收缩率降低到0.3%（但和流程相垂直的方向还要稍高一些）。成型组装的收缩率主要受材料的结晶度和吸湿性影响。实际的收缩率还和塑件设计、壁厚及其它工艺参数成函数关系。
The physical and chemical properties of PA6 are similar to those of PA66. However, its melting point is low and the temperature range of the process is very wide. Its impact resistance and solubility are better than that of PA66, but its hygroscopicity is stronger. Because many quality characteristics of plastic parts are affected by hygroscopicity, we should give full c***ideration to this when using PA6 to design products. In order to improve the mechanical properties of PA6, various modifiers are often added. Glass fiber is a common additive for ***. Sometimes synthetic rubber, such as EPDM and SBR, is added in order to improve its impact resistance. For products without additives, PA6 shrinks between 1% and 1.5%. Adding glass fiber additives can reduce the shrinkage rate to 0.3% (but slightly higher in the direction perpendicular to the process). The shrinkage of molding and assembly is mainly affected by the crystallinity and moisture absorption of the material. The actual shrinkage rate is also related to plastic design, wall thickness and other process
