Tire comprising at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) at least one elastomeric polymer,- (b) at least one layered material, said layered material having an individual layer thickness of from 0.2 nm to 30 nm, preferably of from 0.3 nm to 15 nm, more preferably of from 0.5 nm to 2 nm,- wherein said layered material shows, in a X-ray powder diffraction (XRPD) pattern, a X-ray intensity ratio (R) defined according to the following formula: ( R) = [A(OOl) /A(hkO) max ] x 100 wherein: A(OO1) is the area of the peak (001) ; A(hko)max is the area of the most intense peak (hkO) , at least one of h or k being different from 0 ; lower than or equal to 20, preferably lower than or equal to 15, more preferably lower than or equal to 10, still more preferably lower than or equal to 5. Preferably, said at least one structural element is a tire tread band.

Abstract
Tire comprising at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) at least one elastomeric polymer,- (b) at least one layered material, said layered material having an individual layer thickness of from 0.2 nm to 30 nm, preferably of from 0.3 nm to 15 nm, more preferably of from 0.5 nm to 2 nm,- wherein said layered material shows, in a X-ray powder diffraction (XRPD) pattern, a X-ray intensity ratio (R) defined according to the following formula: ( R) = [A(OOl) /A(hkO) max ] x 100 wherein: A(OO1) is the area of the peak (001) ; A(hko)max is the area of the most intense peak (hkO) , at least one of h or k being different from 0 ; lower than or equal to 20, preferably lower than or equal to 15, more preferably lower than or equal to 10, still more preferably lower than or equal to 5. Preferably, said at least one structural element is a tire tread band.File | Dimensione | Formato | |
