We evaluate antistatic properties using two measures: surface resistance (which is an index of how easily electricity is conducted), and half-life (the amount of time for the static charge to be halved).
The lower the surface resistance (Ω), the higher the antistatic property; and the shorter the half-life (s), the higher the antistatic property.
Surface Resistance (Ω)
The lower the score, the higher the antistatic property
