The invention relates to additives for enhancing the electrical conductivity and physical and mechanical properties of rubber compounds, including, inter alia, the elastic modulus, tensile strength, tear resistance and abrasion resistance of composite elastomer-based materials (rubbers), and to composite elastomer-based materials (rubbers). The invention proposes an additive containing from 1 to 20 wt % carbon nanotubes, from 3 to 90 wt % high-viscosity organic rubber, and from 8 to 95 wt % low-molecular-weight organic dispersion medium. The present invention also proposes a method for producing the additive.

The invention solves the problem of creating a rubber composition that can be used in a solid tyre of an extremely simple and manufacturable design to provide safe and hygienic operation of the tyre without accumulating a static electric charge and without leaving black marks on a floor surface. An electrically conductive rubber composition for non-marking solid tyres is proposed, which composition comprises (1) a rubber or a mixture of at least two rubbers, (2) oxide fillers and modifiers, (3) organic plasticisers and modifiers, (4) a curing system and (5) carbon nanotubes, wherein the total amount of carbon nanotubes and carbon of other allotropic modifications constitutes from 0.05 to 1.5 wt % relative to the amount of rubber. A non-marking solid tyre made from the electrically conductive rubber composition is also proposed.
