PA66美国杜邦 FR50-NC010

用途生产轴承，齿轮，车轮，轴辊，水泵叶轮，风扇叶片，输油管，储油管，绳索，鱼网，变压器线圈

性状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。具有优良的自润滑性，机械强度较高。但吸水性较大，尺寸稳定性较差。

应用于制造机械、汽车、化学与电气装置的零件，如齿轮、滚子、滑轮、辊轴、泵体中叶轮、风扇叶片、高压密封围、阀座、垫片、衬套、各种把手、支撑架、电线包内层等。亦可制成薄膜用作包装材料。还可用于制作医疗器械、体育用品、日用品等。

注模条件干燥处理

如果加工前材料是密封的，那么就没有必要干燥。如果储存容器被打开，那么建议在85℃的热空气中干燥处理。如果湿度大于0.2%，还需要进行105℃，12小时的真空干燥。

Usage: Production of bearings,gears, wheels, shaft rollers, water pump impellers, fan blades, oilpipelines, oil storage pipes, ropes, fish nets, transformercoils

Semitransparent or opaque milkywhite crystalline polymer with plasticity. Density 1.15g/cm3.Melting point 252 ℃. Embrittlement temperature -30 ℃. The thermaldecomposition temperature is greater than 350 ℃. Continuous heatresistance of 80-120 ℃, balanced water absorption rate of 2.5%. Canwithstand corrosion from acids, alkalis, most inorganic salinesolutions, haloalkanes, hydrocarbons, esters, ketones, etc. It hasexcellent self-lubrication and high mechanical strength. However,due to its high water absorption, its dimensional stability ispoor.

Applied in the manufacturing ofmechanical, automotive, chemical, and electrical equipmentcomponents, such as gears, rollers, pulleys, roller shafts,impeller in pump bodies, fan blades, high-pressure sealingenclosures, valve seats, gaskets, bushings, various handles,support frames, wire wrap inner layers, etc. It can also be madeinto thin films and used as packaging materials. In addition, itcan also be used to make medical equipment, sports equipment, dailynecessities, etc.

Drying treatment for injectionmolding conditions

If the material is sealedbefore processing, there is no need to dry it. However, if thestorage container is opened, it is recommended to dry it in hot airat 85 ℃. If the humidity is greater than 0.2%, vacuum drying at 105℃ for 12 hours is also required.
