Anti-static industrial flooring

Graphene nanotubes for ESD floors: standards compliance & flexibility in color and thickness

Industrial floors in high technology sectors, the pharmaceutical and automotive industries, and cleanrooms require anti-static characteristics. Graphene nanotubes provide flooring unmatched performance by granting permanent, homogenous electrical conductivity without hot insulative spots and visual black dots, remaining stable regardless of humidity and allowing the flooring to pass the walking body voltage test. The extremely low dosage of easy-to-use graphene nanotube concentrates makes it possible to maintain the original mechanical abrasion resistance, impact resistance, and chemical resistance of the resin.

How does anti-static flooring work?

How does anti-static flooring work?

An ESD conductive flooring system can be comprised of layers such as copper tape, conductive primer, a base coat, and a thin topcoat. To conduct electrical charge from the surface to the ground, the originally insulative base coat should be made conductive. Self-leveling ESD floors must meet surface-to-surface or surface-to-ground resistance requirements, complying with IEC 61340-4-1, ASTM F150-06, and ANSI / ESD S20.20 standards.

Ultra-strong, ultra-long, electrically conductive and flexible, graphene nanotubes create a 3D conductive network inside the material at extremely low working dosages. This allows them to be a versatile conductive agent offering strong performance on all key parameters.

Low working dosages and flexibility in basecoat thickness

Compared with chopped carbon fiber and conductive mica, the required dosage of which is 5–20 wt.% leading to a higher price, graphene nanotubes make it possible to obtain the required conductivity at much lower working dosages starting from 0.01 wt.%, improving cost efficiency.

Due to the length of chopped carbon fiber (2 mm or longer), the base layer thickness must be at least ~2 mm, which complicates installation and raises costs. Additionally, the fiber’s morphology can potentially create insulating “hot spots.” In contrast, graphene nanotubes can be used with various anti-static flooring systems and thicknesses, ensuring stable, permanent surface-to-ground resistance, ultimately reducing ESD flooring costs.
