PP 聚丙烯的英文名为Polypropylene，简称PP，俗称百折胶。
聚丙烯按其结晶度可分为等规聚丙烯和无规，等规聚丙烯为高度结晶的热塑性树脂，结晶度高达95%以上，分子量在8~15万之间，本书介绍的聚丙烯主要为等规聚丙烯。而无规聚丙烯在室温下是一种非结晶的、微带粘性的白色蜡状物，分子量低（3000~10000），结构不规整缺乏内聚力，应用较少。二、聚丙烯的改性聚丙烯可通过填充，增强，共混，共聚。交联来改性。如添加碳酸钙，滑石粉，无机矿物等填料。可提高刚性，硬度，耐热性和尺寸稳定性；添加玻璃纤维，石棉纤维，云母。玻璃微珠等可提高拉伸强度。并可改善蠕变性。低温抗冲击性；添加弹性体和橡胶等可提高冲击性能，透明性等等。
