聚丙烯(PP)概述及應用、聚丙烯PP的概述一、 聚丙烯概述聚丙烯采用齊格勒-納塔催化劑使丙烯催化聚合而得,它是分子鏈節排列得很規整的結晶形等規聚合物。聚丙烯的英文名為Polypropylene,簡稱PP,俗稱百折膠。聚丙烯按其結晶度可分為等規聚丙烯和無規,等規聚丙烯為高度結晶的熱塑性樹脂,結晶度高達95%以上,分子量在8~15萬之間,本書介紹的聚丙烯主要為等規聚丙烯。而無規聚丙烯在室溫下是一種非結晶的、微帶粘性的白色蠟狀物,分子量低(3000~10000),結構不規整缺乏內聚力,應用較少。二、聚丙烯的改性聚丙烯可通過填充,增強,共混,共聚。交聯來改性。如添加碳酸鈣,*,無機礦物等填料。可提高剛性,硬度,耐熱性和尺寸穩定性;添加玻璃纖維,石棉纖維,云母。玻璃微珠等可提高拉伸強度。并可改善蠕變性。低溫抗沖擊性;添加彈性體和橡膠等可提高沖擊性能,透明性等等。 本公司專業代理以下產品,免費提供COA,SGS,UL黃卡,加工參數 。索取: 銷售直線: 李 :
