pp是一种半结晶的热塑性塑料。具有较高的耐冲击性，机械性质强韧，抗多种有机溶剂和酸碱腐蚀。在工业界有广泛的应用，是平常常见的高分子材料之一。澳大利亚的钱币也使用聚丙烯制作。
pp主要用途
主要用于各种长、短丙纶纤维的生产，用于生产聚丙烯编织袋、打包袋、注塑制品等用于生产电器、电讯、灯饰、照明设备及电视机的阻燃零部件
东标检测中心提示：pp不存在环境应力开裂问题。通常，采用加入玻璃纤维、金属添加剂或热塑橡胶的方法对pp进行改性。pp的流动率mfr范围在1-40。低mfr的pp材料抗冲击特性较好但延展强度较低。对于相同mfr的材料，共聚物型的强度比均聚物型的要高。 由于结晶，pp的收缩率相当高，一般为1.8-2.5。并且收缩率的方向均匀性比pe-hd等材料要好得多。加入30的玻璃添加剂可以使收缩率降到0.7。 均聚物型和共聚物型的pp材料都具有优良的抗吸湿性、抗酸碱腐蚀性、抗溶解性。然而，它对芳香烃（如苯）溶剂、氯化烃（四氯化碳）溶剂等没有抵抗力
