TUBALL™ graphene nanotubes (SWCNTs) are a high-performance additive for styrene-butadiene rubber (SBR) compounds filled with carbon black and used in various types of tires, such as truck, agricultural and others. Nanotubes enhance physical and mechanical properties of SBR and impart required electrical conductivity to rubbers.

Thanks to a number of unique properties, such as high strength, conductivity, flexibility and record length-to-diameter ratio, introducing graphene nanotubes into SBR compounds provides significant benefits in mechanical performance that could not previously be achieved.

For industry users’ convenience, OCSiAl has developed TUBALL™ MATRIX concentrate containing pre-dispersed nanotubes, which is suitable for SBR formulations filled with carbon black. It does not require any changes in standard technological procedures but makes it possible to gain a competitive edge in a rubber’s performance. Adding as little as 1.8% of TUBALL MATRIX leads to significant benefits in modulus, tear strength and electrical conductivity without a negative impact on hysteresis or any other property.
