Abstract: A process for producing tyres for vehicle wheels includes making a raw tyre including at least one crosslinkable elastomeric material, molding the raw tyre in a molding cavity defined in a vulcanization mold, and crosslinking the elastomeric material by heating the tyre to a predetermined temperature for a predetermined time, wherein the raw tyre includes at least one crosslinkable elastomeric material having an elastomeric polymer containing epoxide groups and an active filler containing hydroxyl groups dispersed in the elastomeric polymer, and wherein the crosslinking step is carried out essentially without additional crosslinking agents. A related composition, process for producing the composition, manufactured product, and tyre are also disclosed.

Abstract: A crosslinkable elastomeric composition includes at least one elastomeric polymer including carboxylic groups, and at least one epoxidized elastomeric polymer including greater than or equal to 0.1 mol % and less than or equal to 20 mol % of epoxide groups relative to a total number of moles of monomers present in the at least one epoxidized elastomeric polymer. The composition is crosslinkable in a substantial absence of additional crosslinking agents. A tyre for vehicles includes a carcass structure, a belt structure extended coaxially around the carcass structure, and a tread band extended coaxially around the belt structure. The tread band comprises an external rolling surface intended to come into contact with the ground. In one embodiment of the present invention, the tread band includes at least one crosslinked elastomeric material. A process for producing the tyre is also disclosed.

Abstract: A crosslinkable elastomeric composition includes an elastomeric polymer including epoxide groups and an oligomer of a fatty acid. The composition is crosslinkable substantially in an absence of additional crosslinking agents. Tyres including one or more components made of crosslinked elastomeric material are also disclosed. Additionally disclosed is a process for producing a tyre for vehicle wheels including manufacturing a tyre comprising at least one crosslinkable elastomeric material, subjecting the tyre to moulding in a cavity defined in a vulcanization mould, and crosslinking the at least one elastomeric material by heating the tyre to a predetermined temperature and for a predetermined time. Further, a crosslinked elastomeric product obtained by crosslinking the composition is disclosed.

Abstract: A tyre for a wheel of a vehicle comprises a toroidal carcass provided with axially opposite sidewalls and beads for anchoring the tyre to a rim of the wheel, a tread band located crownwise on the carcass, comprising a surface with a plurality of hollows and grooves defining a raised tread pattern, and a belt structure interposed between the carcass and the tread band, axially extending between the sidewalls. The tread band comprises at least first and second circumferential axially-contiguous portions arranged to contact a road surface. The first portion is formed of a first composition comprising a reinforcing filler having at least 40%-by-weight carbon black and at least some white filler, the second portion is formed of a second composition comprising a reinforcing filler having at least 20%-by-weight white filler, and the first composition is different from the second composition.

Abstract: A method for preparing dental restoration which is to be secured in the mouth of a dental patient includes providing a base plate with ready made x-ray opaque restorative teeth thereon, the base plate being formed in correspondence with the mouth of the patient in which the restorative teeth are to be fixedly secured. The base plate is temporarily situated in the patient's mouth and then the temporarily situated position of the base plate in the patient's mouth is observed, preferably via an x-ray. The temporarily situated position of the base plate in the patient's mouth is assessed to determine predetermined locations at which drill holes for facilitating the fixed securement of the restorative teeth in the patient's mouth are to bored.
