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.
In contrast to other conductive agents, TUBALL™ graphene nanotubes are a versatile conductive agent offering good performance on all key parameters.
Note: this diagram provides average trends compared with other additives, based on OCSiAl data. Product performance may vary depending on product type and formulation.

There is a number of standards related to regulations for ESD protection in safety wear. Graphene nanotubes can be used to achieve all these requirements.
Applications: oil and gas, chemical facilities, pharmaceutical and medical areas, electronics manufacturing, automotive industry, etc.
The extremely low dosage required of graphene nanotubes creates the opportunity to produce colorful solutions where desired.
