Abstract: This paper presents the results of a study on the use of andesite waste as a mineral filler in polymer composite materials. The object of the study is polymer composites based on Latex 2012 and Policril 590, while the subject is the influence of andesite waste concentration on the thermophysical properties of these materials. The aim of the study is to justify the feasibility of secondary utilization of andesite processing waste for the development of composites with enhanced thermal conductivity. Based on the X-ray diffraction pattern of the filler, the crystallite size was calculated, and the dependencies of thermal conductivity on temperature, density, and porosity were investigated at different filler concentrations (65 and 90 wt.%). It was found that at high filler content, effective thermally conductive pathways are formed, ensuring increased thermal conductivity even under elevated porosity conditions. The results confirm the feasibility of incorporating andesite waste into polymer composites and open new opportunities for its use in construction and thermal insulation materials.
