【摘要】 使用α成核剂TMA-3以及聚烯烃弹性体(POE)改善高抗冲共聚聚丙烯(PPK7726、PPK8003)。结果显示,TMA-3成核剂不管是在高流动共聚聚丙烯树脂中,还是在低流动共聚聚丙烯树脂中,均能在缺口冲击强度没有被降低太多的情况下,加快聚丙烯树脂的结晶速度,适度缩短成型周期,提高制品的延展性、刚性、耐热性,赋予制品良好的表面光泽和刚韧平衡性。TMA-3成核剂与聚烯烃弹性体(POE)配合使用,能在几乎不降低制品冲击性能的前提下,明显改善拉伸性能、弯曲性能、耐热性、尺寸均一性。更多还原

【Abstract】 The properties of the high-impact copolymerization polypropylene( PPK7726,PPK8003) were improved by using the alpha-nucleating agent tma-3 and the polyolefin elastomer( POE). And it turns out,TMA-3 nucleating agent either in the high flow copolymerization polypropylene resin,or in the low flow copolymerization polypropylene resin,both can be decreased in the notched impact strength are not too many cases,to speed up the crystallization of polypropylene resin,moderate shorten the molding cycle,improve the ductility and rigidity,heat resistance,gift products good surface gloss and GangRen balance. TMA-3 nucleating agent used with polyolefin elastomer( POE),can reduce the impact properties of products in little premise,significantly improve the tensile properties,bending properties,heat resistance,size uniformity.更多还原
