PA66简介：尼龙（Nylon），中文名聚酰胺，英文名称Polyide（简称PA），是分子主链上含有重复酰胺基团—[NHCO]—的热塑树脂总称。其命名由合成单体具体的碳原子数而定。是美国的化学工业公司──杜邦公司化学家卡罗瑟斯和他的科研小组发明的。 尼龙PA66；聚己二酰己二胺；英文名：Polyide 66，缩写 nylon 66。 CAS编号：32131-17-2 尼龙PA66是PA系列中机械强度、应用广的品种,因其结晶度高,故其刚、耐热都较高.
PA66加工模具温度：建议 80℃。模具温度将影响结晶度，而结晶度将影响产品的物理特。对于 薄壁塑件，如果使用低于 40℃ 的模具温度，则塑件的结晶度将随着时间而变化，为了保持 塑件的几何稳定，需要进行退火处理。
Runner and gate of PA66 processing: because the solidification time of PA66 is very short, the location of gate is very important. The gate dieter should not be less than 0.5 * t (where t is the thickness of the pstic part). If a hot runner is used, the gate size should be smaller than that of a conventional runner, as the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the minimum dieter of the gate should be 0.75.
PA66 对许多溶剂具有抗溶，但对酸和其它一些氯化剂的抵抗力较弱。
PA66 is resistant to many soents, but weak to acids and other Chlorinators.
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，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，一定要考虑吸湿对几何稳定的影响。
PA66 has a high melting point in polyide. It is a semi crystalline crystalline material. PA66 can also maintain strong strength and stiffness at higher temperature. PA66 still has hygroscopicity after molding, and its degree mainly depends on the comition of the material, wall thickness and environmental conditions. In product design, the influence of Hygroscopicity on geometric stability must be considered
Application fields of PA66:
1. It is widely used in machinery, instrumentation, automobile parts, elronic and elrical, railway, household appliances, counication, textile machinery, sports leisure goods, oil pipe, oil tank and some precision engineering products.
2. Elrical and elronic equipment: connor, reel, timer, cover circuit breaker, switch housing base
Automobile: radiator n, door handle, fuel tank cover, air intake grille, water tank cover, lp holder
3. Industrial parts: chair seat, bicycle fre, skate base, textile shuttle, pedal, slide conveyor
