　　性能

　　PA66塑胶原料为半透明或不透明乳白色结晶形聚合物，具有可塑性。密度1．15g/cm3。熔点252℃。脆化温度-30℃。热分解温度大于350℃。连续耐热80-120℃,平衡吸水率2．5%。能耐酸、碱、大多数无机盐水溶液、卤代烷、烃类、酯类、酮类等腐蚀，但易容于苯酚、甲酸等极性溶剂。具有优良的耐磨性、自润滑性，机械强度较高。但吸水性较大，因而尺寸稳定性较

　　PA66是PA系列中机械强度、应用***的品种,因其结晶度高,故其刚性、耐热性都较高。

Huayun Plastics Co. , Ltd. . Characteristic PA66 plastics have a high melting point in polyamide materials. PA66 plastic still has hygroscopicity after molding, PA66 plastic has low viscosity, PA66 plastic thermal property melting point is the temperature of crystallization melting, for crystalline polymer PA66 plastic, show clear melting point, according to the test method, the melting point fluctuated 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, and in order to maintain 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 highest mechanical strength of PA series, the most widely used variety, because of its high crystallinity, so its rigidity, heat resistance are higher. Oh, Shit
