概述
PA塑料(尼龙，聚酰胺)，英文名称:Polyamide
PA的品种繁多，有PA6、PA66、PAll、PAl2、PA46、PA610、PA612、PAl010等，以及近几年开发的半芳香族尼龙PA6T和特种尼龙等很多新品种。
物理性能
比重：PA6 1.14克/立方厘米，PA66 1.15克/立方厘米，PA1010 1.05克/立方厘米
成型收缩率：PA6 0.8-2.5% ，PA66 1.5-2.2%
成型温度：220-300℃
干燥条件：100-110℃/12小时
坚韧、耐磨、耐油、,耐水、抗酶菌、但吸水大
燃烧鉴别方法：火焰上端黄色，下端蓝色，燃烧后塑料熔滴落，起泡，离火后特殊的羊毛，指甲烧焦味和带芹菜味
|
尼龙6： |
弹性好，冲击强度，吸水较大 |
|
尼龙66： |
性能优于尼龙6，强度高，耐磨性好 |
|
尼龙610： |
与尼龙66相似，但吸水小，刚度低 |
|
尼龙1010： |
半透明，吸水小。耐寒性较好。适于制作一般机械零件、减磨耐磨零件、传动零件以及化工、电器、仪表等零件 |
成型性能
1、结晶料，熔点较高，熔融温度范围窄，热稳定性差，料温超过300度、滞留时间超过30分钟即分解。较易吸湿，需干燥，含水量不得超过0.3%。
2、流动性好，易溢料。宜用自锁时喷嘴，并应加热。
3、成型收缩范围及收缩率大，方向性明显，易发生缩孔、变形等。
4、模温按塑件壁厚在20～90度范围内选取，注射压力按注射机类型、料温、塑件形状尺寸、模具浇注系统选定，成型周期按塑件壁厚选定。树脂粘度小时，注射、冷却时间应取长，并用白油作脱模剂。
5、模具浇注系统的形式和尺寸，增大流道和浇口尺寸可减少缩水。
聚酰胺的不足之处在于：由于热膨胀和吸水性所至的尺寸精度不够，耐酸性差，硬度和弹性模量不够。经改良以后，也是比较优秀的工程塑料之一。
应用
汽车制造方面
用于制造燃料滤网、燃料过滤器、罐、捕集器、储油槽、发动机汽缸盖罩、散热器水缸、平衡旋转轴齿轮。也可用在汽车的电器配件、接线柱等。另外，它还可用作驱动、控制部件等。
电器电子工业
可用于制造电饭锅、电动吸尘器、高频电子食品加热器，电器产品的接线柱、开关和电阻器等。
医疗器械仪器
