A composite oxide-based filler with high thermal conductivity and low mechanical wear resistance at the conventional alumina ratio.
The Dipyroxide #7300 series is an alumina-based composite oxide powder (thermal conductive filler) developed by applying our synthetic technology for composite oxide pigments. By combining alumina with a small amount of several metal oxides, it has a higher thermal conductivity compared to alumina. Additionally, its rounded shape and low hardness help reduce wear on molds, molding machines, pumps, and blades or drills used during the processing of molded products, contributing to longer equipment lifespan and prevention of contamination.
