Electrically conductive rubbers with graphene nanotubes: durability, elasticity, and color, with low hardness and no carbon release


TUBALL™ graphene nanotubes, also known as single wall carbon nanotubes, have an effect even at ultra-low dosages starting from just 0.15 wt.% for anti-static, static dissipative and conductive rubber applications.

Improved mechanical properties

TUBALL™ nanotubes, in contrast to traditional conductive agents, minimize the impact on compound elasticity and on tensile parameters, viscosity and rheological properties.

The ultra-low dosage of TUBALL™ makes it possible to use full silica-based formulations and obtain the desired anti-static properties, as well as improved tear strength and tensile performance, without degradation of elastic properties and with the ability to maintain low hardness.
