Polymer-polymer HDPE blends

Abstract

The article presents the results of a study of the addition of high-viscosity unimodal HDPE on the complex of physicochemical, rheological and strength properties of PE100. The analysis of thermal properties according to TGA/DTA data as well as the results of studying the composition of volatile products, and the molecular weight characteristics of individual components and blends are presented. The conducted studies have shown that the introduction of high-viscosity unimodal HDPE into bimodal PE100 makes it possible to control the rheological characteristics of the material, shifting the “melt breakdown” to the area of high shear rates, i.e. to increase the processability of the original PE 100, and expand the processing range, which may be useful in the production of extruded sheets and profile products. At the same time, the strength characteristics of the finished product will remain at the level of PE100.
