Anti-static and reinforcing agent for electrically conductive NBR

TUBALL graphene nanotubes are a high-performance anti-static agent and reinforcing filler for nitrile butadiene rubber. TUBALL makes it possible to create NBR compounds with stable conductivity and improved mechanical performance.

The most important feature of graphene nanotubes for NBR is the ability to impart stable conductive properties while avoiding most of the negative impacts on hardness and elongation that result from the use of standard anti-static agents, such as multiwall carbon nanotubes, most types of carbon black and polymer-based anti-static additives. The reason for this is graphene nanotubes’ unique properties, which allow them to create a reinforcing and conductive 3D network inside rubbers, even at extremely low working dosages, which also guarantee no carbon release on the surface of the material.

As little as 2% of TUBALL MATRIX concentrate, containing pre-dispersed nanotubes, is enough to significantly improve NBR compound mechanical properties and impart anti-static properties. TUBALL MATRIX was specially designed by OCSIAl to allow easy introduction of nanotubes without any changes to standard formulation.
