TUBALL™ nanotubes are a unique anti-static agent that provides electrical conductivity at low dosages not achievable with any standard conductive additive. Textiles with improved electrical conductivity are used to avoid the hazards of electrostatic discharge (ESD) and can achieve the anti-static performance required by safety regulations.

TUBALL™ graphene nanotubes are available in various forms depending on the industrial application: the easy-to-use additive TUBALL™ MATRIX, which is a line concentrates based on polymer carriers and pre-dispersed TUBALL™ graphene nanotubes, and TUBALL™-based liquid-phase suspensions with properly dispersed and stabilized graphene nanotubes.

TUBALL™ graphene nanotubes: Good performance on all key parameters

Key benefit 1: Compliance with industrial safety regulation

There are number of standards related to regulations for ESD protection in safety wear. Graphene nanotubes can be used to achieve all these requirements.

EN ISO 18080, EN 1149, EN 61340, EN 16350, ANSI/ESD STM2.1, Directive 1994/9/EC and ATEX Directive 95, GOST 19616, GOST 12.4.124 and others;
Depending on the relevant standard, the textile type and the final application, generally the resistance needs to be in the range of 10⁵–10¹¹Ω;
Applications: oil and gas, chemical facilities, pharmaceutical and medical areas, electronics manufacturing, automotive industry, etc.

Key benefit 2: Colored anti-static compounds

The extremely low dosage required of graphene nanotubes creates the opportunity to produce colorful solutions where desired.
