介绍：PA66又称尼龙66，俗称尼龙双6；聚己二酰己二胺；英文名：Polyamide 66，缩写 nylon 66

PA66塑胶原料为半透明或不透明乳白包或带黄色颗粒状结晶形聚合物，具有可塑性.

PA66在聚酰胺材料中有较高的熔点。在产品设计时，一PA66的收缩率在1%~2%之间

PA66在较高温度也能保持较强的强度和刚度。

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。

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。

优点:1、具高抗张强度 2、耐韧、耐冲击性特优 3、自润性、耐磨性佳、耐药品性优 4、低温特性佳 5、具自熄性

理性化：密度（g/cm3） 1．10-1．14；拉伸强度(MPa) 60. 0-80．0；洛氏硬度118；熔点252℃；脆化温度-30℃；热分解温度大于350℃；连续耐热80-120℃。冲击强度（kJ/m2） 60-100；静弯曲强度(MPa) 1 00-120；马丁耐热(℃) 50-60；弯曲弹性模量 (MPa) 2000～3000；体积电阻率（Ωcm） 1.83×1015；平衡吸水率2．5%；介电常数 1．63

广泛应用于机械、仪器仪表、汽车部件、电子电气、铁路、家电、通讯、纺机、体育休闲用品、油管、油箱及一些精密工程制品。电子电器：连接器、卷线轴、计时器、护盖断路器、开关壳座汽车：散热风扇、门把、油箱盖、进气隔栅、水箱护盖、灯座工业零件：椅座、自行车输框、溜冰鞋底座、纺织梭、踏板、滑输

PA66 2021GW3 法国罗地亚工艺条件

Drying: if the processing of the material is sealed, it is not necessary to dry. However, if the storage container is opened, it is recommended that drying in hot air at 85 ℃. If the humidity is higher than 0.2%, also requires 105 ℃, 12 hours vacuum drying

The melting temperature: 260~290 ℃. The glass additive products for 275~280 ℃. The melting temperature should not be higher than 300 ℃. Mold temperature: 80 ℃. Mold temperature affects the crystallinity, and the crystallinity will affect the physical characteristics of the product. For thin wall plastic parts

Injection pressure: normally in 750~1250bar, depending on the material and product design

Injection speed: speed (for enhanced materials should be slightly lower).

The runner and gate: due to the solidification time of PA66 is very short, so that the gate position is very important. Gate diameter not less than 0.5T (where t is the thickness of plastic parts). If you use hot runner, gate size than the use of conventional channel should be smaller, because the hot runner can help prevent premature solidification material. If using submarine gates, the minimum diameter of the gate should be 0.75mm. A typical use of PA66 is more widely used in the automotive industry, instrument shell and other needs to have the impact resistance and high strength requirements of the product.

Transparent or opaque white crystalline polymers, with plasticity. The density of 1.15g\/cm3. The melting point of 252 DEG C. The brittle temperature of -30 ℃. The thermal decomposition temperature greater than 350 ℃. Continuous heat resistant 80-120 ℃, balance water absorption rate of 2.5%. Acid, alkali, most inorganic salt solution, Halon, hydrocarbons, esters, ketones and other corrosion
