摘要： An optical fibre comprising: an optical waveguide comprising a glass core surrounded by a glass cladding; a coating surrounding said optical waveguide comprising a polymer material comprising a cured polyester obtained by: (a) esterification of a reactant (A) selected from carboxylic acids, triglycerides, and mixtures thereof, having a C16-C24 aliphatic chain comprising at least two conjugated double bonds, with a reactant (B) selected from polyols having at least 3 hydroxyl groups, the polyols being thermally stable up to 300°C; (b) curing of the 10 so obtained polyester, in the presence of a transition metal salt, the transition metal being selected from Mn, Fe, Co, Cu, and Ni. Preferably, the step of curing is a thermal curing, preferably up to 300°C. The transition metal salt acts as curing accelerator, i.e. it increases the curing rate so as to match the optical fibre drawing speed, the temperature of the glass exiting the drawing step and the drawing tower height commonly used in industrial plants for optical fibre production.

摘要： A flame-retardant electric cable (10) is disclosed, the cable having a core comprising an electric conductor (11) and an electrically insulating layer (12) made from a flame-retardant polyolefin-based composition comprising: a) a cross-linked polyolefin as base polymer; b) silica; and c) carbon nanotubes wherein the amount of silica is from 5wt% to 10wt% of the polyolefin- based composition, and the amount of carbon nanotubes is from 0.5wt% to 2wt% of the polyolefin-based composition. Such a cable has improved flame retardant performances, especially regarding a lower occurrence of droplets during burning, which render it capable of being certified in higher classes of the current international standards, for example of the standard EN 50399:2011/A1 (2016).
