Mixing Ratio

The properties of a silicone-based elastomeric thermal pad filled with inexpensive ceramic additives were studied in this research. The effects of the content, particle size and mixing ratio of two additives upon the thermal and di-electrical property of the thermal pad are investigated. The result shows that the higher the content, the higher the thermal and dielectric properties are. In addition, the thermal conductivity of two particles filled thermal pads are higher than that of a single particle filled thermal pad. The thermal conductivity of the two kind of particle sizes (14 and 2 um) of 60 % (vol.) SiC filled thermal pad is the highest (2.14 W/m·K).

Polymeric Samples

In this article, epoxy-based dielectric materials for solid insulator were investigated. First, epoxy-based polymeric samples with different permittivities were prepared by incorporating a mixture of two fillers (Al2O3 and SrTiO3) into epoxy matrix. Then, dielectric properties were characterized for the epoxy-based samples by using a dielectric spectrometer with varied frequency. Finally, breakdown tests were performed under AC voltage to characterize the breakdown strength of the dielectric material. Results indicated that the permittivity (dielectric constant) of epoxy-based materials can be adjusted only by changing the mixing ratio of two types of fillers. On the other hand, the obtained dielectric materials showed acceptable breakdown strength with the present amounts of fillers.
