PA66 A H2 FR HF2 阻燃、_产品资讯

PA66 A H2 FR HF2 性状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，但易溶于苯酚、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，因而尺寸稳定性较差。

颗粒：

广泛用于制造机械、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、电线包层等。亦可制成薄膜用作包装材料。此外，还可用于制作医疗器械、体育用品、日用品等。
