Functional properties of fillers

Fillers have many special functions, which are shown in:
A Optical properties: light reflectivity. Fillers have good light reflectivity, which can make the filled objects bright and beautiful. Fluorescent fillers can display logos in dark places, and the difference in refractive index can enhance or weaken the light;
B Thermal properties: including the thermal conductivity, specific heat capacity, thermal expansion, thermal stability of the filler, etc. directly affect the thermal properties of the filler;
C Electrical properties: There is a difference between the theoretical and actual conductive properties of the filler. This is due to the presence of hydroxyl groups on the surface of the filler, free ions adsorbed on the surface, impurities of variable-valence metal compounds, etc. When using, these factors should be considered. The impact on the performance of the filled object.
