Porous diatomite particles with different diameters were used as functional materials in various field. This study investigated effect of diatomite particles on the physical properties of foamed EVA (ethylene vinyl acetate). Formed EVA resin was modified using the different weight percentages of diatomite (0.1, 1.0, 3.0, 5.0 and 10.0 wt.%). Tensile test, tear test and compression test were used to investigate mechanical properties. The results showed that tensile strength and tear strength of the EVA/diatomite composites were generally improved compared to the pure EVA, and the strength of both composites increased with the amount of diatomite. However, the compression strength of the EVA/diatomite composites was lower than that of the pure EVA. It was found that the porous diatomite particles did not affect the compression strength of the EVA/diatomite composites.
