The antistatic performance of antistatic cleanroom shoes relies primarily on the conductive design of the sole and upper materials. Soles are typically made from polymer materials such as PVC, SPU, or PU; conductive components-such as conductive fibers or carbon powder-are incorporated to create conductive pathways that rapidly dissipate static electricity. For instance, PVC soles offer high wear resistance, while PU soles are lighter and more elastic, allowing for selection based on the specific application environment. Uppers are generally made of canvas (offering good breathability) or leather (offering high durability); both materials undergo antistatic treatment to prevent static generation caused by friction. Conductive insoles or straps may also be included inside the shoe to further enhance conductivity.
Conductivity Mechanism: Conductive materials (such as carbon black or conductive fibers) are incorporated into the sole to form a pathway connecting the wearer's body to the ground, thereby dissipating static electricity.
Resistance Range: Surface resistance is typically maintained within the 10⁶–10⁹ Ω range; this effectively eliminates static electricity while preventing the risk of electric shock.
Usage Environment: These shoes must be used in conjunction with antistatic flooring to ensure a complete grounding circuit is established between the human body, the shoes, and the ground.
