In the study, fillers were selected as sameclass grain distribution and mixed with orthophtalic based PE resin to produce composites. The thermalcharacterization of the composites was determined with thermogravimetric and thermal conductivity.Chemical characterization was carried out with FT-IR. Compressive strength was investigated withUniversal Testing Machine. SEM device was used to investigate the morphological alterations of thecomposites. Also, statistical analysis was carried out for thermal conductivity and mechanical results. Atthe end of the present study, some minor chemical alterations were seen in FT-IR after the interaction ofthe fillers and PE resin. Thermal stability decreased after adding fillers. The thermal conductivity andthermogravimetric analysis were not agreed with each other that higher thermal conductivity was seen inthe PE-Q composites. The compressive strength of filler-based composites was higher than that of the neatPE composite whereas the higher compressive strength was obtained in the PE-Q. This study confirms theapplicability of various fillers as a reinforcing agent in the polymer.en10.18466/cbayarfbe.787883info:eu-repo/semantics/openAccess[No Keywords]Article1717989
