This article clarifies that the influence of volcanic particles (VPs) and calcium carbonate particles (CaCO 3 ) on the scratch behavior of high‐density polyethylene (HDPE). Melt compounding was carried out using a twin‐screw microcompounder and then injection molding with various VPs and CaCO 3 contents such as 0, 6, 12, 18, and 24 wt% was performed for preparing test samples. Scratch testing was performed using the testing apparatus and methodology outlined in ASTM D7027–05 with 60 mm/min scratch velocities of 200 μm stainless steel ball bearing scratch tip. Coefficient of friction (COF) and scratch hardness values of various VPs‐ and CaCO 3 ‐filled HDPE composites were determined. Results showed that COF and scratch hardness values were improved with higher inorganic particle concentrations. It was found that VPs was more effective filler for the scratch properties of HDPE than CaCO 3 . After scratch tests, scratch damage mechanisms were analyzed by scanning electron microscopy. POLYM.
