Abstract

In the present work the physico-mechanical and technological characteristics of polymer composite materials based on linear low-density polyethylene with various dispersed fillers with increased thermal conductivity, such as zinc oxide, aluminium powder, silicon carbide and boron nitride, have been investigated for the purpose of further developments in the field of increasing the thermal conductivity of polymers and creating polymer composites with a given complex of properties. The results of introduction of fillers into the polymer in a wide concentration range from 5 to 60 wt. % were analysed. Also due to the different influence of fillers on the properties of polymer composition, an experiment on the joint introduction of some fillers was carried out. In the course of work such characteristics of polymer compositions as strength and relative elongation at break, tensile yield strength, tensile modulus of elasticity, as well as Shore hardness, density and melt flow index were investigated, as it is an important indicator of recyclability of developed compositions. In the course of the research, the optimum concentration of each type of filler was determined and the possibility of creating highly filled compositions based on thermoplastics was evaluated in order to create optimal conditions for maximum heat transfer.
