Abstract: Sensor mesh suitable for use in a system for the detection of a puncture in a tyre, said sensor element having a wire structure arranged as a net comprising a first set of wires arranged according to a first direction (A) and a second set of wires arranged according to a second direction (B), in order to form meshes (M) of said net structure, wherein said wires of said first set of wires are of electrically non-conductive material and said wires of said second set of wires are of electrically conductive material, said wires of electrically conductive material being electrically connectable to each other in order to form a circuit configuration (c1, c2, c3, c4, c5), each of said meshes (M) having an inner area (AM) of between 0.25 mm2 and 100 mm2.

Abstract: A compound for a tyre sealant layer comprising at least one polymer base consisting of an essentially saturated polymer and a filler, which in turn comprises kraft lignin.

Abstract: Tyre sealant layer made from a rubber compound comprising at least a polymer base and a filler comprising a magnetic material in the form of nanoparticles with dimensions of between 1 and 100 nm.

Abstract: A method for making rubber portions comprising tyre metallic reinforcing plies. This method comprises an incorporation step wherein metallic cords which constitute the plies are arranged between two skim layers and a treatment step for the metallic cords, that precedes the incorporation step and wherein the metallic cords are wetted with a diene elastomeric polymer with a viscosity of between 3 and 10 Pa·s at room temperature.

Abstract: A belt for tyres comprising a ply made up of metal cords and two layers of tread ply skim arranged to cover the ply. The ply is coated with a protective composition comprising at least one cross-linkable unsaturated-chain polymer base and a surface-active compound. The protective composition is derived from an aqueous-based suspension applied to said ply. The tread ply skim comprises the same cross-linkable unsaturated-chain polymer base present within the protective composition.

Abstract: A method to produce a compound for a tyre sealant layer, comprising a swelling step, during which a crumb rubber is immersed in a process oil chosen among the ones belonging to the families of paraffin process oils, naphthene process oils or natural process oils, so as to obtain a crumb rubber that swells due to the absorption of the process oil; and a following mixing step, during which said swollen crumb rubber is mixed with at least one polymer base consisting of an essentially saturated polymer.

Abstract: A paint having high thermal conductivity to be applied to the outer surface of a tire. The paint consists of a rubber compound having a thermal conductivity greater than or equal to 0.2 Wm?1K?1, a viscosity of between 0.5 and 10000 cP and an elasticity modulus less than or equal to 8 MPa.

Abstract: A compound for a tyre sealant layer comprising at least one polymer base consisting of an essentially saturated polymer and a filler, which in turn comprises kraft lignin.
