细数汽车用塑料的那些事
随着汽车轻量化的发展趋势，塑料在汽车中的比例越来越高。一部车下来，汽车塑料总用量可占汽车自重的5%～10%。下面就为大家“分解”一部车，看看汽车中哪些部位都用了什么塑料。
汽车内饰系统材料
仪表、门板用低VOC耐刮PP/EPDM T20，立柱用PP T20，门拉手及底座用电镀PC/PBT、PC/PBT GF，中控装饰件用电镀ABS、PC/ABS
汽车外饰系统材料
保险杠用PP/EPDM T15，侧裙用免喷涂PP/EPDM T20，翼子板用PPO/PA，轮毂盖板用PA6 MD20，格栅用耐候ASA，后视镜壳体用半芳香族尼龙，挡泥板用TPE
发动机周边材料
发动机罩盖用PA6 MD20，进气歧管用PA GF30，水室用耐醇解PA66 GF30，副水箱用耐黄变PP
HVAC系统材料
空调壳体用PP T20，冷却风扇罩用PP GF30，风扇叶片用PA66 GF30
汽车照明系统材料
车灯壳体用PP T30、耐热ABS，配光镜用PBT/PET，面罩用改性PMMA，支架用增强PPS。

沙伯基础PPO

成型工艺
 1) 非结晶料、吸湿小，PPO的吸水率很低，但水分会使制品表面出现银丝、气泡等缺陷，为此，可将原料置于80~100℃的烘箱中，干燥1-2h后使用。
  2)PPO的分子键刚性大，玻璃化转化温度高，不易取向，但强迫取向后很难松弛。所以制品内残余内应力较高，一般要经过后处理。
  3)PPO为无定型材料，在熔融状态下的流变性接近于牛顿流体，但随温度的升高偏离牛顿流体的程度越大。
  4)PPO熔体的粘度大，因此加工时应提高温度，并适当提高注射压力，以提高充模能力。
  5)PPO的回料可重复使用，一般重复使用3次，其性能没有明显降低。
  6)对PPO熔体宜采用螺杆式注塑机成型，喷嘴采用直通式为佳，孔径为3-6mm
  7)在PPO注塑成型时，宜采取高压、高速注射，保压及冷却时间不能太长。
  8)模具的主流道宜采用较大的锥度或采用拉料钩，浇道以短粗为好。
  9)浇口宜采用直接式、扇形或扁平形，采用针状浇口时直径应适当加大，对于长浇道可采用热流道结构。
  10)PPO的成型收缩率较小，一般为0.2%一0.7%，因而制品尺寸稳定性能优良。
  11)流动性差，为类似牛顿流体，粘度对温度比较敏感，制品厚度一般在0.8毫米以上。极易分解，分解时产生腐蚀气体。宜严格控制成型温度，模具应加热，浇注系统对料流阻力应小。
  12)聚苯醚的吸水率很低0.06%左右，但微量的水分会导致产品表面出现银丝等不光滑现象，最好是作干燥处理，温度不可高出150℃，否则颜色会变化。
  13)聚苯醚的成型温度为280-330℃，改性聚苯醚的成型温度为260-285℃。 PPO塑胶原料注塑工艺熔料温度：270-290℃
