Intermediate and Low Density Low-Pressure Polyethylenes: Their Properties and Applications in the Wire and Cable Industry

摘要

The polyethylene resins described in this paper possess a unique balance of properties. They combine the desirable features of conventional low-density polyethylene with those of high-density polyethylene, yet they suffer few of the limitations of either. Moreover, they exhibit some outstanding advantages possessed by neither conventional nor high-density resins. They provide excellent physical properties without sacrifice in ESCR or thermal embrittlement resistance. In achieving these improvements it has been necessary to cast aside traditional considerations of melt index and density, further illustrating the fact that these parameters are not true measurements of important physical properties.
