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℃。熔化温度应避免高于 300℃。
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 processing mold temperature: recoended 80 ℃. Mold temperature will aff the crystallinity, which will aff the physical properties of the product. For thin-walled pstic parts, if the mold temperature is lower than 40 ℃, the crystallinity of the pstic parts will change with time. In order to maintain the geometric stability of the pstic parts, annealing treatment is needed.
Basic physical properties of PA66: PA66 is still the most important variety. The melting point, tensile strength, bending strength and hardness of PA66 are the highest in the nylon fily, so it is widely used in various fields. It can also maintain strong strength and stiffness at higher temperature. The melting point of PA66 is 260 ℃; it is a semi crystalline crystalline material. PA66 is resistant to many soents, but weak to acids and other Chlorinators. The shrinkage of PA66 is between 1% and 2%, which can be reduced to 0.2% - 1% by adding gss fiber additive. PA66 has low viscosity, so it has good fluidity. This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. It still has hygroscopicity after molding, and its degree mainly depends on the comition of the material, wall thickness and environmental conditions. The influence of Hygroscopicity on geometric stability must be considered in product design.
