Abstract
The present invention relates to elastomeric compositions for tyres and relative compounds, components and tyres comprising them, said compositions comprising an elastomeric polymer, a phenolic product, optionally already partially cross-linked, optionally an aldehyde and/or at least a methylene donor product and an oxidised carbon allotrope as a cross-linking catalyst. Advantageously, this catalyst is able to complete the cross-linking reactions of the phenolic resins in the conventional times and conditions of vulcanisation, or even more rapidly, providing mechanically stable compounds.
