    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 water-soluble polymer coating for application to electrical wiring used in aircraft and other electrical structures is provided. The coating includes a water-soluble polymer such as polyvinyl acetate, polyvinyl alcohol, and methyl cellulose which is dissolved in water to form a solution. The solution may be applied to electrical wiring during manufacturing and dried to a film such that if the wire becomes damaged and exposed to water, a protective water-insoluble deposit is formed on the wiring. Alternatively, the solution may be applied to wiring which is already damaged to form a protective water-insoluble deposit.
