An additive for incorporation into a rubber product as filler or extender which is a carbonaceous and/or siliceous powder or fibrous material derived from plant or vegetable materials, such as bagasse or other waste materials. The additive is produced by processing the plant or vegetable material to form an ash material and thereafter treating the ash material to produce a carbonaceous and/or siliceous powder or fibrous material of required particle size. A rubber product containing the additive may also incorporate further components such as processing aids, coupling agents, etc. |
