It determines the lossiness of the medium. Similar to dielectric constant, low loss tangents result in a "fast" substrate while large loss tangents result in a "slow" substrate.Beware that the exact values can vary greatly depending on the particular manufacturer's process, so you should ...

The dielectric constant & relative permittivity are key to the operation of capacitors. Find out how they affect capacitors; formulas, definitions; details . . . .
It is desirable that the material has stable electrical characteristics (dielectric constant and dissipation factor) across a broad frequency range. The most common materials used are polyethylene (PE), polypropylene (PP), fluorinated ethylene propylene (FEP), and polytetrafluoroethylene (PTFE). PE ...
