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.
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.
Zytel® PA66/6应用运动用品使用的塑料：
头盔制造商 DXL-Protion 选择杜邦™ Zytel®尼龙树脂的原因是它的高耐受、刚和韧。 这款超韧尼龙采用了 33% 的玻璃纤维进行强化。 采用 Zytel® 制造的四个头盔零件分别是外壳、头部周围的 C 形“扣带”和两个侧外壳。 获得专利的四部件设计使这种头盔比传统的单部件头盔更适合头部。
PA66 process: drying: if the material is sealed before processing, there is no need to dry. However, if the storage container is opened, drying in hot air at 85 ℃ is recoended. If the humidity is higher than 0.2%, vacuum drying at 105 ℃ for 12 hours is required. Melting temperature: 260 ~ 290 ℃. For gss additive products, 275 ~ 280 ℃. The melting temperature should not be higher than 300 ℃.
