塑料- 影响着每天的日常生活
就增长速度而言,没有哪一种用量相当的材料能够与塑料相提并论。世界各地的塑料需求量增长速度均高与各国国内生产总值的增长速度。究其原因,那就是如果我们想满足日常生活需求,并且让生活越来越舒适,塑料是我们的不二选择。对于食品包装和运输、房屋的建造和保温、家用电器、交通或休闲活动等领域的应用,塑料都是首选材料。

汽车应用概述
PA6在汽车上应用广泛,汽车是塑料重要和快速增长的市场,PA6具有良好的综合性能,密度低,容易成型,设计自由度大,隔热绝缘,而且在模具和组装成本上也有明显的优势。PA6不仅拉伸强度高、冲击性能优而且热变形温度高、耐热、摩擦系数低,耐磨损、自润滑、耐油、耐化学性能优,而且特别是适于用玻纤或其他材料填充增强改性,提升材料性能和档次,满足最终部件和客户需求。目前PA6汽车制品种类繁多,如散热器箱、前格栅、加热器箱、散热器叶片、转向柱罩、尾灯罩、吸附罐、定时齿轮外罩、风扇叶片、各种齿轮、散热器水室、空气滤清器外壳、进气歧管、控制开关、进气导管、真空连接管、安全气囊、电气仪表外壳、刮水器、泵叶轮、轴承、衬套、阀座、车门把手、车轮罩等,总之,涉及汽车发动机部件、电气部件、车身部件和安全气囊等多部位。其中汽车发动机罩下零部件用量最大,这是由于汽车向小型化、轻量化发展,发动机室体积缩小,温度升高,要求机罩下部件更耐高温,而PA6通过改性,能充分达到上述要求。有工业分析家认为PA6部件不仅起保护作用,还有美观作用。
