摘要
开发了线型低密度聚乙烯(LLDPE)薄膜专用树脂DFDA-8042KJ,并与国内外同类树脂进行了比较。DFDA-8042KJ树脂熔体流动速率为1.5～2.5g/10min,密度为0.917～0.923g/cm^3,拉伸屈服应力大于或等于8.3 MPa,拉伸断裂应变大于500%,灰分小于或等于0.04%,雾度小于或等于14%。加工应用表明,DFDA-8042KJ树脂适用于易开口薄膜的生产,满足用户要求。
A grade of linear low density polyethylene for films, DFDA-8042KJ, was developed and compared with its domestic and overseas counterparts. The resin had melt flow rate of 1.5-2.5 g/10 min, density of 0.917- 0.923 g/cm3, tensile strength at yield not lower than 8.3 MPa, elongation at rupture higher than 500%, ash content not more than 0.04%, haze equal to or less than 4%. The processing and application show that the speciality resin is suitable for manufacturing antiblocking films and can meet consumer demand.
