PA66 plastic raw materials



PA66 美国杜邦 101F ZytelPA66 美国杜邦 101F Zytel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性，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，一定要考虑吸湿性对几何稳定性的影响。为了提高PA66的机械特性，经常加入各种各样的改性剂。玻璃就是最常见的添加剂，有时为了提高抗冲击性还加入合成橡胶，如EPDM和SBR等。 PA66的粘性较低，因此流动性很好（但不如PA6）。这个性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对许多溶剂具有抗溶性，但对酸和其它一些氯化剂的抵抗力较弱。具有超强的抗冲击性，韧性，耐负60度低温，适合做滚轮，阀体，雪橇鞋和工程零部件，无声齿轮等。 注塑模工艺条件

PA66 in polyamide materials have higher melting point. It is a half crystal - crystal materials. PA66 in high temperature can also keep strong strength and stiffness. PA66 in forming is still hygroscopicity, its degree depends on the material composition, wall thickness and environmental conditions. In the product design, be sure to consider hygroscopicity of geometric stability, the influence of. In order to improve the mechanical properties of PA66, often to join all kinds of modifying agent. Glass is the most common additives, sometimes in order to improve the impact resistance also join synthetic rubber, such as EPDM and the SBR, etc. PA66 viscosity is low, the liquidity is very good (but not as PA6). This property can be used to process very thin element. Its viscosity to temperature changes very sensitive. PA66 of shrinkage rate between 1% ~ 2%, join glass fiber additive can reduce shrinkage rate to 0.2% ~ 1%. Shrinkage in the flow direction and flow direction phase vertical direction of the phase difference is bigger. PA66 for many solvent has good solubility, but to acid and some other chlorinating agent resistance is weak. With super impact resistance, toughness and resistance to negative 60 degrees low temperature, suitable for roller, body, sled shoes and engineering parts, silent gear, etc. Injection mold process conditions

PA66 美国杜邦 101F Zytel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85C的热空气中干燥处理。如果湿度大于0.2%，还需要进行105C，12小时的真空干燥。
