Antistatic Agent

Definition & Mechanism

Antistatic Agent – A functional additive that reduces or eliminates static electricity by:

Forming a conductive surface layer to dissipate chargesIncreasing material surface conductivity (10⁶–10¹² Ω/sq)Preventing dust adhesion and electrostatic discharge (ESD) risks
