Graphene nanotubes for anti-static textile coatings: ESD safety in compliance with international standards

imageimage

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

In contrast to other conductive agents, TUBALL™ graphene nanotubes are a versatile conductive agent offering good performance on all key parameters.

Parameter Ammonium compounds Carbon black TUBALL™ NANOTUBES

Key benefit 1: Compliance with industrial safety regulations

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 105–1011 
  • 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.

0.25-1.5 wt.% TUBALL MATRIX 814 beta for 109-105 Ω/sq with maintained color

OCSiAl internal PVC plastisol formulation. Sample thickness: 2 mm. ASTM D257

Coloured anti-static nitrile film with 0.06 wt.% TUBALL™

Surface resistivity 107 Ω/sq

Key benefit 3: Standard processing and mixing equipment

TUBALL™-based products can be processed with standard equipment widely used by textile manufacturers.

Other benifits

  • No carbon release on surface
  • Permanent and stable level of resistivity
  • No negative influence on mechanical properties
  • Minimally affects density, viscosity and other rheological properties of formulations
  • Resistivity is independent of humidity
