产品详细信息

PA 66塑料原材料

与PA6相比，PA66更多地用于汽车行业、仪表外壳和其他要求抗冲击性和高强度要求的产品。用于制造机械、汽车、化工和电气设备的零件，如齿轮、滚柱、滑轮、滚柱轴、泵体中的叶轮、风扇叶片、高压密封外壳、阀座、垫片、衬套、各种手柄、支架、金属线包内层、，等。
性能
PA66塑料材料是一种半透明或不透明的乳白色结晶聚合物，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%。耐酸、碱、大多数无机盐溶液、卤代烷烃、碳氢化合物、酯、酮等，但易溶于苯酚和甲酸等极性溶剂。具有优良的自润滑性能和较高的机械强度。但吸水率大，尺寸稳定性差。PA66是PA系列的机械强度。由于其结晶度高，其硬度和耐热性高

应用

高温电气插座零件、电气零件、齿轮、轴承、滚柱、弹簧支架、滑轮、螺栓、叶轮、风扇叶片、螺旋桨、高压密封垫片、阀座、油管、储油容器、绳索、扎带、传动带、砂轮粘合剂、电池盒、绝缘电气零件、线芯、拉丝、，等。

PA 66 Plastic Raw Material

Product Details

PA 66 Plastic Raw Material

PA66, compared with PA6, PA66 is more used in the automotive industry, instrument housings and other products that require impact resistance and high strength requirements. Parts used in the manufacture of machinery, automobiles, chemical and electrical devices, such as gears, rollers, pulleys, roller shafts, impellers in pump bodies, fan blades, high-pressure sealing enclosures, valve seats, gaskets, bushings, various handles, Support frame, inner layer of wire package, etc.
performance
PA66 plastic material is a translucent or opaque milky white crystalline polymer with plasticity. Density 1.15g/cm3. Melting point 252 ℃. Embrittlement temperature -30 ℃. Thermal decomposition temperature is greater than 350 ℃. Continuous heat resistance 80-120 ℃, equilibrium water absorption rate of 2.5%. It is resistant to acid, alkali, most inorganic salt solutions, halogenated alkanes, hydrocarbons, esters, ketones, etc., but it is easy to be soluble in polar solvents such as phenol and formic acid. It has excellent self-lubricating property and high mechanical strength. However, the water absorption is large, so the dimensional stability is poor. PA66 is the mechanical strength of the PA series. Because of its high crystallinity, its rigidity and heat resistance are high.

application

High temperature electrical socket parts, electrical parts, gears, bearings, rollers, spring brackets, pulleys, bolts, impellers, fan blades, propellers, high pressure sealing gaskets, valve seats, oil pipes, oil storage containers, ropes, cable ties, transmission belts , Grinding wheel adhesive, battery box, insulating electrical parts, wire core, wire drawing, etc.
