Founded in 1802 A company in the United States is a scientific research company. With its own innovative products, raw materials and services, it has demonstrated international level scientific research and engineering project capability for the world's sales market, and helped to solve various international challenges, including providing sufficient and healthy food for people all over the world and reducing dependence on non renewable resources, And its maintenance of life and the natural environment, so that people all over the world and all over the country have a happier, safer and healthier daily life. DuPont's business process covers more than 90 countries and regions all over the world, involving agriculture, animal husbandry and food, housing and engineering construction, communication and transportation, power, energy and microbial application of high technology and many other industries with common product innovation and service projects
为了提高 PA66 的机械特，经常加入各种各样的改剂。玻璃就是常见的添加剂，有时为了提高抗冲击还 加入合成橡胶，如 EPDM 和 SBR 等。
In order to improve the mechanical properties of PA66, various modifiers are often added. Gss is the most coon additive, and sometimes synthetic rubber, such as EPDM and SBR, is added to improve the impact resistance.
PA66加工的流道和浇口:由于 PA66 的凝固时间很短，因此浇口的位置非常重要。浇口孔径不要小于 0.5*t（这里 t 为塑件厚度）。如果使用热流道，浇口尺寸应比使用常规流道小一些， 因为热流道能够帮助阻止材料过早凝固。如果用潜入式浇口，浇口的小直径应当是0.75。
PA66具有优良的耐磨、自润滑，机械强度较高。但吸水较大，因而尺寸稳定较差
PA66 has excellent wear resistance, self lubrication and high mechanical strength. However, the size stability is poor because of its high water absorption
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。
PA66应用领域：
1、广泛应用于机械、仪器仪表、汽车部件、电子电气、铁路、家电、通讯、纺机、休闲用品、油管、油箱及一些精密工程制品。
2、电子电器：连接器、卷线轴、计时器、护盖断路器、开关壳座
汽车： 散热风扇、门把、油箱盖、进气隔栅、水箱护盖、灯座
3、工业零件：椅座、输框、溜冰鞋底座、纺织梭、踏板、滑输
