甲基排列在分子主链的同一侧称等规聚丙烯, 聚丙烯树脂若甲基无秩序的排列在分子主链的两侧称无规聚丙烯,当甲基交替排列在分子主链的两侧称间规聚丙烯。一般工业生产的聚丙烯树脂中,等规结构含量约为95%,其余为无规或间规聚丙烯。工业产品以等规物为主要成分。聚丙烯也包括丙烯与少量乙烯的共聚物在内。通常为半透明无色固体,无臭无毒。由于结构规整而高度结晶化,故熔点可高达167℃。耐热、耐腐蚀,制品可用蒸汽消毒是其突出优点。密度小,是最轻的通用塑料。缺点是耐低温冲击性差,较易老化,但可分别通过改性予以克服。 共聚物型的PP材料有较低的热变形温度(100℃)、低透明度、低光泽度、低刚性,但是有更强的抗冲击强度,PP的冲击强度随着乙烯含量的增加而增大。PP的维卡软化温度为150℃。由于结晶度较高,这种材料的表面刚度和抗划痕特性很好。PP不存在环境应力开裂问题。PP的熔体质量流动速率(MFR)通常在1~100。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,共聚型的抗冲强度比均聚型的要高。由于结晶,PP的收缩率相当高,一般为1.6~2.0%。性质描述 中文名: 聚丙烯[1]聚丙烯结构图3D模型中文别名:丙纶;聚丙烯纤维;丙纶短纤维;聚丙烯短纤维;丙纶短纤;丙纶fdy;丙纶长丝fdy;烟用聚丙烯过滤丝束油剂[2] 英文名: Polypropylene 缩 写: PP 化学式: (C3H6)n CAS号: 9003-07-0 密 度: 0.91g/cm3 熔 点: 164~170℃
