The working principle of anti-static rubber mats primarily relies on a dual-layer composite structure that facilitates both static conductivity and static dissipation. By controllably discharging electrostatic charges, it prevents the accumulation of static electricity, thereby safeguarding sensitive electronic components or flammable and explosive environments from the hazards of electrostatic discharge.

• Double-layer structure design:
• Surface layer (static dissipation layer): The resistance value is typically 10*6⁶–10*9⁹ Ω, which can slowly and safely conduct away the electrostatic charges on the surface of the contacted object, avoiding sparks generated by instantaneous discharge.
• Bottom layer (conductive layer): With a lower resistance value (≤10*6⁶ Ω), it serves as a rapid conductive pathway, quickly directing the charges collected on the surface layer to the grounding system.
• Grounding discharge path:
• The anti-static rubber mat must be reliably connected to the public grounding point (with a grounding resistance typically required to be ≤10Ω) through a grounding wire (such as an alligator clip or grounding buckle).
• The electrostatic charge flows from the charged object → the surface layer of the mat → the bottom layer → the grounding wire → the earth, achieving safe and controllable discharge.
• Material characteristics:
• Nitrile rubber (NBR) is commonly used as the base material, with conductive carbon black, metal fibers, or antistatic agents added to adjust the electrical resistance properties.

The surface can be either matte or glossy, and it possesses industrial applicability such as wear resistance, oil resistance, acid and alkali resistance, and anti-aging properties.
