聚丙烯(PP)概述及應(yīng)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(jié)排列得很規(guī)整的結(jié)晶形等規(guī)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(jié)晶度可分為等規(guī)聚丙烯和無規(guī),等規(guī)聚丙烯為高度結(jié)晶的熱塑性樹脂,結(jié)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(guī)聚丙烯。而無規(guī)聚丙烯在室溫下是一種非結(jié)晶的、微帶粘性的白色蠟狀物,分子量低(3000~10000),結(jié)構(gòu)不規(guī)整缺乏內(nèi)聚力,應(yīng)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(lián)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(wěn)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(yè)代理以下產(chǎn)品,免費提供COA,SGS,UL黃卡,加工參數(shù) 。索取: 銷售直線: 李 :
