What materials are used for anti-static shoes?
The materials used in anti-static shoes are primarily categorized into two parts: the sole and the upper. The core requirement is the electrical conductivity of the sole.
I. Sole Materials (The critical conductive component): Soles typically achieve static dissipation through the addition of conductive agents (such as conductive carbon black). Three common materials include: PU (Polyurethane): Soft, lightweight, and elastic; offers a comfortable fit along with good wear resistance and slip resistance. PVC (Polyvinyl Chloride): Relatively low cost and slightly stiffer; wear-resistant; commonly used in standard cleanrooms. SPU: A new material combining the advantages of PU and PVC; offers a balance of lightness, elasticity, and moderate pricing, along with high comfort. Conductive Rubber: Rubber infused with carbon black; features excellent elasticity, high wear resistance, and a long service life; suitable for heavy industry or environments requiring frequent walking.
II. Upper Materials: The upper must complement the sole to prevent static accumulation. Common materials include: Anti-static fabric/mesh: Fabrics woven with conductive fibers (such as carbon fiber filaments); offers good breathability. Canvas/Leather: Canvas or high-quality leather treated with anti-static properties; suitable for various work environments and seasonal needs.
