    摘要： Tyres for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary —NH2 and secondary —NH— amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector. Furthermore, by suitably modifying the compound compositions in the reinforced structural elements and, possibly, also in the other elastomeric components of the tyre, it is possible to manufacture tyres while avoiding the use of toxic chemicals, such, as resorcinol and formaldehyde.

    摘要： Tire comprising: - a carcass structure of a substantially toroidal shape, having opposite lateral edges associated with respective right-hand and left-hand bead structures, said bead structures comprising at least one bead core and at least one bead filler; - a belt structure applied in a radially external position with respect to said carcass structure; - a tread band radially superimposed on said belt structure; - a pair of sidewalls applied laterally on opposite sides with respect to said carcass structure, - at least one structural element selected from bead filler, sidewall insert, tread underlayer, obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) a crosslinkable elastomeric base comprising at least about 30 phr, preferably from about 50 phr to about 100 phr, of at least one elastomeric polymer including from about 0.05% by weight to about 10% by weight, preferably from about 0.1% by weight to about 5% by weight, with respect to the total weight of the elastomeric polymer, of at least one functional group selected from carboxylic groups, carboxylate groups, anhydride groups, ester groups; (b) from about 2 phr to about 50 phr, preferably from about 5 phr to about 30 phr, of at least one layered inorganic material.

    摘要： Tyre (10) for motorcycles comprising a carcass structure (2), a belt structure (5) and a tread band (8), wherein the tyre (10) having a transverse curvature ratio (f/C) of at least 0.20; the belt structure (5) comprises at least one belt layer comprising a plurality of reinforcing cords (13) arranged substantially parallel to one another and inclined with respect to the equatorial plane of the tyre; the reinforcing cords (13) being made of lyocell yarns or ends, wherein the belt cords are arranged such that the product between the diameter of the cords expressed in millimetres and the density of the cords in the belt layer expressed as number of cords per decimeter is between about 40 and about 70.
