Microbeads are described, comprising silica fibres with needle-shaped morphology of nanometric size, characterised by reduced dustiness and good dispersibility in elastomeric materials, a process for the preparation thereof and the use thereof in the production of vehicle tyres.

Microbeads comprising silicate fibres with needle-shaped morphology of nanometric size, preparation thereof, elastomeric compositions and tyres for vehicles comprising them

A tire for vehicle wheels, includes at least one structural element obtained by crosslinking a crosslinkable elastomeric composition including at least one vulcanized rubber in a subdivided form surface treated with at least one oxidizing agent; at least one diene elastomeric polymer, and at least one sulfur-based vulcanizing agent. A surface treatment process of vulcanized rubber and crosslinkable elastomeric composition is obtained with the vulcanized rubber in a subdivided form surface treated with at least one oxidizing agent.

Tire for vehicle wheels comprising crosslinked elastomeric composition

A tire includes at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition including: (a) an amount higher than or equal to 30 phr, preferably 40 phr to 100 phr, of at least one polyisoprene rubber; (b) an amount lower than or equal to 70 phr, preferably 0 phr to 60 phr, of at least one diene elastomeric polymer other than the polyisoprene rubber (a); (c) an amount higher than or equal to 30 phr, preferably 40 phr to 120 phr, of at least one carbon black reinforcing filler; (d) 0.2 phr to 10 phr, preferably 1 phr to 5 phr, of at least one copolymer of at least one ethylenically unsaturated carboxylic acid or a derivative thereof with at least one ethylenically unsaturated monomer containing at least one polyoxyalkylene side chain. Preferably, the structural element is a tire's sidewall.

Tire and crosslinkable elastomeric composition

Optical fiber has a glass portion and at least one coating of crosslinked polymer material surrounding the glass portion, the coating being obtained by crosslinking a composition of (a) at least one radically crosslinkable oligomer containing at least two reactive functional groups and having a number average molecular weight lower than about 1,000, preferably between about 400 and about 900; (b) at least one cationically crosslinkable compound containing at least one reactive functional group; (c) at least one free radical photoinitiator; and (d) at least one cationic photoinitiator. Preferably, the coating is a secondary coating or, in the case of a ribbon of optical fibers, it is a common polymer coating known as a 'common coating'.

Optical fiber with polymeric coating crosslinked in the presence of both radical and cationic photoinitiators

An optical fiber having: a) a glass portion; and b) at least one protective coating layer disposed to surround the glass portion, the protective coating layer having a modulus of elasticity value between &#x2212;40&#xb0; C. and +60&#xb0; C. between 5 MPa and 600 MPa, preferably not higher than 500 MPa, more preferably not higher than 450 MPa and much more preferably not higher than 300. Preferably the protective coating layer is a single protective coating layer which is disposed in contact with the glass portion.
