PA66(聚酰胺66或尼龍66)，同PA6相比，PA66更廣泛應用于制造機械、汽車、化學與電氣裝置的零件，如齒輪、滾子、滑輪、輥軸、泵體中葉輪、風扇葉片、高壓密封圍、閥座、墊片、襯套、各種把手、支撐架、電線包內層等。
PA66塑膠原料為半透明或不透明乳白色結晶形聚合物，具有可塑性。密度1.15g/cm3。熔點252℃。脆化溫度-30℃。熱分解溫度大于350℃。 連續耐熱80-120℃,平衡吸水率2.5%。能耐酸、堿、大多數無機鹽水溶液、鹵代烷、烴類、酯類、酮類等腐蝕，但易容于苯酚、甲酸等極性溶劑。具有優良的耐磨性、自潤滑性，機械強度較高。但吸水性較大，因而尺寸穩定性較差。
PA66 is a high mechanical strength and widely used variety in PA series. Because of its high crystallinity, its rigidity and heat resistance are high. PA66 has high melting point in polyamide. It is a semi-crystalline-crystalline material. PA66 also maintains high strength and stiffness at higher temperatures. PA66 still has hygroscopicity after molding, and the degree of hygroscopicity mainly depends on the material composition, wall thickness and environmental conditions. The influence of hygroscopicity on geometric stability must be considered in product design. Various modifiers are often added to improve the mechanical properties of PA66. Glass is a common additive, sometimes added to improve the impact resistance of synthetic rubber, such as EPDM and SBR. PA66 is less viscous and therefore has good (but not as good) mobility. This property can be used to machine very thin components. Its viscosity is sensitive to changes in temperature. The shrinkage rate of Pa66 was 1% ~ 2% , and the shrinkage rate could be reduced to 0.2% ~ 1% by adding glass fiber additive. The difference of shrinkage rate between the flow direction and the vertical direction of the flow direction is large.
