  • Patent number: 11756701
    Abstract: A cable contains a core including a transmissive element and a coating layer made of a coating material. The coating material contains, with respect to the total weight of polymeric materials present in the composition, (i) 70% to 95% by weight of a recycled linear low density polyethylene (r-LLDPE); and (ii) 5 to 30% by weight of an ethylene-vinyl acetate copolymer (EVA). The EVA may be added to the r-LLDPE or, alternatively, be already contained in the r-LLDPE as a result of previous LLDPE use. The cable may further contain a skin layer placed around and in direct contact with the coating layer based on r-LLDPE.

    Abstract: A cable contains a core including a transmissive element and a coating layer made of a coating material. The coating material contains, with respect to the total weight of polymeric materials present in the composition, (i) 70% to 95% by weight of a recycled linear low density polyethylene (r-LLDPE); and (ii) 5 to 30% by weight of an ethylene-vinyl acetate copolymer (EVA). The coating layer shows mechanical properties comparable to those of a virgin polymer composition and better, both before and after ageing, than recycled polymer-based compositions containing recycled LLDPE but free from EVA. The EVA may be added to the r-LLDPE or, alternatively, be already contained in the r-LLDPE as a result of previous LLDPE use. The cable may further contain a skin layer placed around and in direct contact with the coating layer based on r-LLDPE.
