Preface

In today's market, heat management is a huge challenge, and traditional thermal conductive materials often struggle to meet increasingly stringent requirements. Among the constantly emerging high school thermal conductive fillers, there are different performance and types: some require high thermal conductivity, some have ordinary thermal conductivity but are suitable for mid to low end fields, and some have excellent performance but are expensive... Among so many types of thermal conductive fillers, how to choose the most suitable filler?

△ Magnesium oxide

1. Oxide filler spherical magnesium oxide vs. spherical aluminum oxide

##Spherical magnesium oxide

Magnesium oxide has good insulation, heat resistance, and thermal conductivity; Compared with it, the advantage of spherical magnesium oxide thermal conductive powder lies in its high filling rate and high packing density, which helps to improve the thermal conductivity of thermal conductive materials.

##Spherical alumina

The cost of alumina is low, but its filling amount is small, so the thermal conductivity of the finished product is very limited; Although the filling amount of spherical alumina is relatively large, its strong viscosity will limit its use in certain applications that require a large amount of filling.

△ Thermal conductivity of common oxide fillers

In the modern market, magnesium oxide has a wide range of material sources. Coated spherical magnesium oxide thermal conductive powder is not only softer than aluminum oxide, but also has a thermal conductivity about twice that of ordinary aluminum oxide; Spheroidized magnesium oxide particles can better fill the polymer matrix, reduce interfacial contact thermal resistance, and thus improve overall thermal conductivity.
