机械强度、刚度、硬度、韧性高等特点。耐老化性好，机械减振能力好，良好的滑动性，优异的耐磨性，机械加工性能好，高化学稳定性，抗有机溶剂和燃油，无毒无害。以及高耐热不形变性（适用温度范围-40度---120度）。尼龙是五大工程塑料中应用最广的品种。
High mechanical strength, rigidity, hardness and toughness. Good aging resistance, good mechanical shock absorption, good sliding, excellent wear resistance, good machining performance, high chemical stability, anti organic solvents and fuel oil, non-toxic and harmless. And high heat-resistant deformation (applicable temperature range - 40 ℃ -- 120 ℃). Nylon is one of the five most widely used engineering plastics.
PA66+ 二硫化钼（灰黑色）：含二硫化钼粉末，可在不影响未改性铸型尼龙的耐冲和耐疲劳性能的同时，提高其承载能力和耐磨性，它非常广泛地用来制造齿轮、轴承、星轮和套。
PA66 + molybdenum disulfide (gray black): containing molybdenum disulfide powder, it can not affect the impact resistance and fatigue resistance of unmodified mold nylon, but also improve its bearing capacity and wear resistance. It is widely used to manufacture gears, bearings, starwheels and bushings.
