TUBALL™ graphene nanotubes (also known as single wall carbon nanotubes) are the most effective anti-static agent available, offering a unique combination of stable conductivity and good mechanical performance in elastomers.
Unlike conventional conductive additives such as multi wall carbon nanotubes, carbon fibers, and most types of carbon black, which have significant drawbacks in tensile and elastic properties due to a high loading level, graphene nanotubes create a 3D reinforcing conductive network in elastomers to provide stable conductivity without drawbacks, and at the same time allow the production of colored products and maintain or even improve mechanical properties.

An extremely low working dosage of TUBALL™ graphene nanotubes enables a full range of electrical resistivity from <10 to 1010 Ω·cm, allowing the production of both conductive and anti-static elastomers. Being produced in the form of ready-to-use products containing pre-dispersed nanotubes, TUBALL™ dispersion does not require any changes to standard processing and mixing equipment.
Graphene nanotube-based elastomers have applications in many industries, where durable and ESD-protected products are required, including cleanrooms, the oil & gas, automotive, electronics, tires, mining, and chemical industries.
The TUBALL™-based product line for elastomers includes solutions for silicones, latexes, and various types of conductive rubbers.
