LL0220AA是以丁烯-1为共聚单体的线性低密度聚乙烯共聚物。LL0220AA是专门为生产手包和其他铸造拉伸薄膜,如定向带而开发的。它也可以作为低密度聚乙烯或低密度聚乙烯在铸造和吹塑薄膜应用中的混合伙伴。LL0220AA采用铸造挤压工艺加工具有以下优点:机械性能平衡好。良好的光学性能。贴附性能好。LL0220AA还可用作低压电力电缆绝缘或光纤护套的化合物。LL0220AA应在为LLDPE设计的机械中加工。铸造过程中的熔化温度范围通常为240°C-280°C,吹塑薄膜的贫混合物的熔化温度范围为165°C-215°C。LL0220AA应存放在50°C以下的干燥条件下,避免阳光直射。*LL0220AA适用于食品接触。 LL0220AA is a linear low density polyethylene copolymer containing butene-1 as a co-monomer. LL0220AA has been specially developed for production of hand wrap and other cast stretch films such as oriented tapes. It can also be used as a blending partner in LDPE or LLDPE in both cast and blown film applications. LL0220AA offers the following advantages when it processed by the cast extrusion process: Good balance of mechanical properties. Good optical properties. Good cling performance. LL0220AA also can be used as compounds for low voltage power cable insulation or fibre optic jacketing. LL0220AA should be processed in machinery designed for LLDPE. Melt temperature range in the cast process are normally 240°C-280°C and in lean blends for blown film are 165°C-215°C. LL0220AA should be stored in the dry condition below the 50°C and avoided from the exposure of direct sunlight. * LL0220AA is suitable for food contact. |
