Abstract
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.
