A submicron zinc oxide powder was modified by hexadecyltrimethoxysilane, and a thermal con-ductive PA6 plastic was prepared by the modified zinc oxide and PA6, and its properties were studied. The results show that the oil absorption value of the modified zinc oxide decreases by 67% compared to the unmodified powder. The modified zinc oxide is well distributed in the PA6 matrix, and the PA6 plas-tic show good melt flowability. When the volume fraction of the modified zinc oxide is 25%, the PA6 plastic show good thermal conductive and insulating properties, with the thermal conductivity of 1.05 W/(m·K) and the volume resistivity of 7.29×1010Ω·m.
