PA66美国杜邦 HTN52G35HSL  加纤增强 热稳定级

PA66 的粘较低，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 goodas PA6). This property can be used to process very thin components.Its viscosity is sensitive to temperature changes. The shrinkage ofPA66 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 inthe process dirion and in the dirion perpendicur to the processdirion is rger.

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 semicrystalline crystalline material. PA66 can also maintain strongstrength and stiffness at higher temperature. PA66 still hashygroscopicity after molding, and its degree mainly depends on thecomition of the material, wall thickness and environmentalconditions. In product design, the influence of Hygroscopicity ongeometric stability must be considered
