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
PA66工艺：干燥处理：如果加工前材料是密封的，那么就没有必要干燥。然而，如果储存容器被打开，那么建议在 85℃ 的 热空气中干燥处理。如果湿度大于 0.2%，还需要进行105℃，12 小时的真空干燥。 熔化温度：260~290℃。对玻璃添加剂的产品为275~280℃。熔化温度应避免** 300℃。
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.
Our company has been supplying the following nylon models for a long time：
PA66 and PA6 are the main varieties of nylon, oupying an absolute dominant ition. ong the five engineering pstics, PA66 and PA6 he the rgest yield, the most varieties and the most widely used varieties. Nylon 6 is polycaproct, while nylon 66 is polyhexanediine, and nylon 66 is 12% harder than nylon 6; next are nylon 11, nylon 12, nylon 610, nylon 612, and nylon 1010, nylon 46, nylon 7, nylon 9, and nylon 13. New varieties include nylon 6I, nylon 9t and special nylon MXD6 (barrier resin). There are many varieties of nylon modified, such as reinforced nylon, nylon 610 and nylon 612 Monomer casting nylon (MC nylon), reaction injion molding (RIM) nylon, aromatic nylon, tranrent nylon, high impact (super tough) nylon, elropted nylon, conductive nylon, fle retardant nylon, blends and alloys of nylon and other polymers meet different special requirements, and are widely used as substitutes for traditional materials such as metal and wood.
PA66 的粘较低，因此流动很好（但不如 PA6）。这个质可以用来加工很薄的元件。 它的粘度对温度变化很敏感。PA66 的收缩率在 1%~2%之间，加入玻璃纤维添加剂可以将收缩率降低到 0.2%~1% 。收缩率在流程方向和与流程方向相垂直方向上的相异是较大的。
PA66 has low viscosity, so it has good fluidity (but not as good as PA6). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The shrinkage of PA66 is in the range of 1% ~ 2%, and it can be reduced to 0.2% ~ 1% by adding gss fiber additive. The difference of shrinkage rate in the process dirion and in the dirion perpendicur to the process dirion is rger.
