TUBALL™ nanotubes improve the physical and aging properties of rubbers and provide the required electrical conductivity.

TUBALL™ graphene nanotubes are applied via the easy-to-use additive TUBALL™ MATRIX, which is a line of concentrates based on polymer and plasticizer carriers and pre-dispersed TUBALL™ 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.

Carbon black-based formulation. Improvement of mechanical properties and conductivity

Key benefit 1: Improving mechanical stability after heat/fuel aging

Carbon black-based formulation

Key benefit 2: Retain colors without carbon release to surface

Conductive rubber elastomers are used in production areas with automated systems and sensors where color and anti-static properties are required.

When using carbon black, because of the high concentration required (10% or more) and the spherical shape of the particles, a phenomenon known in the industry as “carbon release” takes place, where the conductive additive is present on the surface of the sample.

In contrast, graphene nanotubes, owing to their greater length-to-diameter ratio, are not released to the surface.

Key benefit 3: Standard processing and mixing equipment

The optimal mixing option is to introduce TUBALL™ MATRIX at the last compounding stage on a 2-roll mill.

Other benefits

• Superior conductivity
• Processing without dust
• Available for extrusion grades
• Minimum effect on hardness
• Possibility of colored anti-static non-marking compounds
