PA66是PA系列中机械强度最高、应用最广的品种,因其结晶度高,故其刚性、耐热性都较高。
特性编辑
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主要用于汽车、机械工业、电子电器、精密仪器等领域。从最终用途看，汽车行业消耗的尼龙66占第一位，电子电器占第二位。大约有88%的尼龙66通过注射成型加工成各种制件，约12%的尼龙66则通过挤出、吹塑等成型加工成相应的制品。

PA66 is the highest mechanical strength and most widely used variety in the PA series. Due to its high crystallinity, it has high rigidity and heat resistance.
Property editing
PA66 has a high melting point in polyamide materials. It is a semi crystalline material. PA66 can maintain strong strength and stiffness at higher temperatures. PA66 still has hygroscopicity after molding, and its degree mainly depends on the material composition, wall thickness, and environmental conditions. When designing products, it is important to consider the impact of moisture absorption on geometric stability.
In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubber such as EPDM and SBR are added to improve impact resistance
PA66 is mainly used in fields such as automobiles, mechanical industry, electronics, precision instruments, etc. From the perspective of end use, nylon 66 consumed by the automotive industry ranks first, while electronic appliances rank second. about 88% of nylon 66 is processed into various parts through injection molding, while about 12% of nylon 66 is processed into corresponding products through extrusion, blow molding, and other molding processes.
