PA66塑料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塑料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。PA66塑料的粘性较低，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。

The shrinkage of Huayun plastics PA66 is between 1% ~ 2% . The shrinkage can be reduced to 0.2% ~ 1% by adding glass fiber additive. The difference of shrinkage in the process direction and in the direction perpendicular to the process direction is large. The melting point of thermal property of PA66 plastics is the temperature of crystallization melting. The melting point of crystalline polymer PA66 plastics is clear. According to the test method, the melting point fluctuates in the range of 259 ~ 267 °C. The melting point of PA66 plastics measured by DTA is 264 °C. The melting temperature range of nylon-66 is 246 ~ 263 °C if the temperature at which the volumetric expansion coefficient shows its maximum value is taken as the melting point. Approximate theoretical melting temperature 259 °C.

 INJECTION MOLDING CHARACTERISTICS OF PA66 PLASTICS DRYING TREATMENT: 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 85C is recommended. If the humidity is greater than 0.2% , 105C, 12 hours of vacuum drying is also required. Melting temperature: 260 ~ 290C. The product of glass additive is 275 ~ 280C. The melting temperature should not be higher than 300 °C. Mold temperature: recommended 80C. Mold temperature will affect the degree of crystallinity, which will affect the physical properties of the product. For thin-walled plastic parts, if the mold temperature is lower than 40 °c, the crystallinity of the plastic parts will change with time. In order to keep the geometric stability of the plastic parts, annealing treatment is needed. INJECTION PRESSURE: usually between 750 and 1250 BAR, depending on material and product design. INJECTION RATE: High (slightly lower for reinforced materials). Runner and gate: The location of the gate is important because PA66 has a short setting time. Gate aperture should not be less than 0.5 * T (where t is the thickness of the plastic part) . If a hot runner is used, the gate should be smaller than a conventional runner because the hot runner helps prevent premature solidification of the material. If a submerged gate is used, the minimum diameter of the gate should be 0.75 mm. PA66 PLASTIC APPLICATION PA66 is the most widely used variety of PA series in mechanical strength. Because of its high crystallinity, its rigidity and heat resistance are both high, high temperature electrical socket parts, electrical parts, gears, bearings, rollers, spring bracket, pulley, bolt, impeller, Fan Blade, propeller, high pressure seal gasket, valve seat, oil pipe, oil storage container, rope, tie belt, transmission belt, grinding wheel adhesive, battery box, insulation electrical parts, wire core, wire pulling and so on
